Interview Clinical Chemistry 62:1 12–19 (2016) By Misia Landau An Interview with David Millington David Millington was born under a lucky star. To hear him tell it, his life story consists of one serendipitous event after another. Certainly from a historical point of view, he has been at the right place at the right time. In 1941, just three years before he was born, the Americans George Beadle and Edward Tatum made a discovery that paved the way for the modern science of molecular biology. Mutating genes in Neurospora, a type of red bread mold, they were able to alter specific enzymes in the metabolic pathways of the mold, thereby confirming a hypothesis put forth in 1902 by the British physician Archibald Garrod that hereditary diseases are due to “inborn errors of metabolism.” This discovery was followed 20 years later—just as Millington was entering college—when the American microbiologist Robert Guthrie came up with the first blood test for phenylketonuria (PKU), which opened up the field of newborn screening. Millington wrote his own chapter in the tale in the late 1980s when he and colleagues had the idea to apply the cutting-edge technique of tandem mass spectrometry to the analysis of newborn blood samples. Their work—which has saved thousands of lives not just in North America but worldwide—revolutionized the field of newborn screening, turning it from a backwater into a scientific success story. In 2011, the Centers for Disease Control called newborn screening one of the great public health achievements of the past 10 years. Millington, who held the post of Medical Research Professor of Pediatrics and Director of the Biochemical Genetics Laboratory at Duke University Medical Center, spoke with me from his office in early July. He had just retired after over 30 years of service. This is a great moment—you’ve just retired! Two days ago. After a long and illustrious career. I don’t know (laughs). It’s not all that illustrious, to be honest with you. It’s a perfectly ordinary career. I just got lucky enough to be in the right place at the right time to make an impact on a particular field. That’s probably true of many scientists born in my time period, because you’re looking at a new technology. In terms of mass spectrometry, I was in on the ground floor. © 2015 American Association for Clinical Chemistry 12 David Millington You were born in 1944 in the town of Bury near Manchester, England. It’s now part of Greater Manchester but in those days it had its own identity as a town. My dad married my mum during the war and then went off and fought on two fronts—Germany and then India. My mum and he had three children. I’m the middle one so you could call me a war baby. Did the war cast a shadow on your childhood? The postwar period was an unusual time, probably the only time in recent history when you could say almost everybody was in the same boat. They were all struggling. Men who had come back from the war were trying to find jobs. My dad was a roofing contractor— he installed roofing tiles— until he found a better job with a building company as a representative. I thought we were special because we were one of the first families that had a car in the streets. Had the Millingtons lived in the same area for generations? My dad’s family were definitely long-time residents. Millington is quite a common name in Lancashire. My mum was born in Cardiff. She was working in a hotel. My dad was on leave and he met her in this hotel, called the Carlton. It was the posh hotel in Cardiff at that time. Interview They started dating and got married around the time that the war broke out. Then they had these three children who didn’t see much of him until he came home from the war. When did he come back? In ’45. He was drafted in late ’39. He was trained as a signalman. That meant he would be up near the front lines, which was kind of dangerous. Was he especially adept with technology? To be able to receive Morse code and transmit it at 21 words a minute—that was the minimum and I think he was faster than that. He had a skill that not many people could get to grips with. Would you trace your interest in technology to your dad? Certainly there’s a gene there. My grandfather also was very interested in technology. He always had a mechanized transport, either a motorcycle or a car. That was fairly unusual for the time. My dad, as I said, was one of the first on our street to own a car. We were one of the few families that could escape on the weekend and take day trips. Where did you go? Local beauty spots—the seaside, the beach. Blackpool and Southport were popular destinations. Were you the first in your family to show an interest in science? My father talked about a relative of his, an uncle, who was one of the lead scientists at ICI [Imperial Chemical Industries], which was one of the big pharmaceutical or chemical companies in England. I was certainly the first of my generation in the family to go to university. Going to university was quite rare. Less than five percent of the young population, if I’m not mistaken, actually got a place in university in the early ’60s. To get a PhD, you’re talking about fractions of a percent. Would anyone have predicted that you would be among that five percent? Maybe one or two of my teachers. I didn’t. I just happened to be a bright student who was interested in everything. I was lucky enough to go to a good school, Canon Slade Grammar. There was an entrance exam. It was relatively small, which set you on a course of being connected with good teachers. Those teachers inspired me. Many of the students that were in the top stream, and I got into the top stream, would go on to university. That was the expectation. All of it was paid for under scholarships—there were no parents or students paying for any of this. I read that the school was founded a hundred years earlier in 1855 and that its motto is “Ora et labora.” Pray and work. Were you required to pray at school? No. The requirement to attend that school was that you have a connection with the church there—it had to be the Church of England. My father was brought up as a Methodist in the Church of England but he was not a devout Christian in any way. Neither am I. I made up my own mind about Christianity and what I believed in. I’m not really a true believer, to be honest, but I liked the exposure to that environment. We had assembly every morning and we would sing hymns, and of course there were school rules and school uniforms. I liked that structure. It put you in awe of the system. You didn’t challenge it so you became a part of it. The focus on the academic environment that that presents is valuable. You mentioned good teachers. Did any spark your interest in science? Teaching of science was not the highest priority in that particular school—it was more classics. But they had appointed new teachers with science degrees the year I came. One of the teachers was a physics teacher, a Welsh teacher by the name of Mr. Goronwy Jones. He had a strong personality. He was actually a bit scary, but a darn good teacher. He, more than anybody, influenced my interest in science. Canon Slade focused on the classics so you must’ve explored the humanities and arts. We were required to do Latin and English language and English literature. Also, French and German. Most of our curriculum was required—there was very little choice. But I did choose to do Russian and music. I’m interested in music yet I have no musical talent whatsoever. What is it about music that resonates with you? Its structure and architecture, especially the classic composers—Mozart, Beethoven. I was unusual in my time. I’m the only kid I knew that was interested in classical music from when I first heard it at the age of about ten. I couldn’t get enough. On the BBC radio, there used to be quite a lot of classical music, so I would listen to that on my own. You described the intellectual appeal of the music but it must’ve had an emotional pull as well. Yes, these classical tunes would go around in my head like pop tunes go around in other people’s head. I think music is a language. It resonated with me. I could see and understand what the music was trying to tell. It’s like I could sense the emotions that were being transmitted by the Clinical Chemistry 62:1 (2016) 13 Interview composers. Some people could see in art, in pictures, what life meant. I could hear it in music. Did you play an instrument? I tried the violin. One day my teacher recorded my playing. That was the day that I decided to quit. Does your affinity for music relate to more general aspects of how your mind works? I was always interested in astronomy. There were astonishing discoveries being made about the stars and the heavens. Reading about that was more incredible than any science fiction. The reality of the discoveries coming out about stars, supernovae, pulsars, quasars, the expanding universe, the structure of the universe and the structure of atoms—all that was interesting to me. My mind would see order in things and like to make sense of it. When did you become interested in chemistry? I was making meals in the kitchen when I was ten for my family. That’s chemistry to me. I wanted to understand what was behind the processes of flour rising, for example. Our school science curriculum was based on fundamental principles. You were either going to be a physicist, which I thought was going to be too challenging. Or mathematics, which is even more challenging. Or chemistry. I chose chemistry because I thought it would get me into the life sciences. At school it didn’t fascinate me all that much because it was not very well taught. At college a light bulb came on. You went to the University of Liverpool in 1962. Liverpool required you to do both physics and chemistry and one other subject in the first year. I had this idea all along that I was going to take chemistry so I focused on chemistry and stayed with it. How did you become interested in mass spectrometry? The last year of your bachelor’s degree, it’s called the honors year, you get assigned to a professor to do a science project. The person I was assigned to, Dr. Robert Johnstone, happened also to be the custodian of the university’s mass spectrometer. I started reading about it and its applications. It was the applications in the life sciences that interested me the most. Liverpool in the early sixties was the home of the Beatles. Did you ever see them perform? I never saw them play at the Cavern but I did get tickets to see a concert just outside of Liverpool. When I got there you couldn’t get in—you couldn’t hear or see anything, it was so packed. The din was phenomenal from the screaming. The thing about being at the University of Liverpool was there was music everywhere. If you walked down the street where I lived, if you walked down any street in that 14 Clinical Chemistry 62:1 (2016) district, you could hear on any given evening at least one band practicing. There were so many of them. On the weekends when the University had its dances, you had about five groups on the bill. On the top of the bill was somebody quite well known and the others were would-be rock bands, trying out. The students were actually the deciders of whether they would make it. Think of all the names—the Moody Blues, the Beatles, the Searchers, the Seekers, Gerry and the Pacemakers, plus many others. They all had to make it in Liverpool. Did you have a favorite group? I preferred the Stones because I felt they spoke to the generation. They were out there and a bit more coarse but they were real. They were renegades. But the musical talent that I was exposed to at Liverpool University was amazing. I saw Ella Fitzgerald, Duke Ellington, Dave Brubeck and his quartet, and many others. There was also soccer in Liverpool—and Manchester, come to think of it. Were you interested in sports? I was interested in two sports growing up as a kid. One of them was golf. My dad was interested in golf and when I saw what golf was all about, I immediately took to it. What is golf about? Golf is about learning how to grow up. It’s the most difficult game of all. What makes it so difficult? You’re hitting an object with a singularly unsuitable other object, the golf club. You have to learn how to move your body in such a way to make proper contact. You’re on an open course with no barriers. Every hole is different. Every time you play the course is different because wind, rain, the conditions of the sky all affect the game. It really is a challenging game. When you play, it can be very frustrating. You see people losing their tempers. You learn how to control your emotions. You learn how to accept reality—you can’t be perfect at this game. Is there a connection to science? Well, you’re certainly on your own in the sense that it’s not a team game and you’re fighting your own demons. Your ability and skill level all play a role, but you’re really battling against yourself. A lot of it is in your head. It teaches you the value of being patient and diligent. And of practice. What was the other sport? Cricket. It’s a team sport and a very English one. I wasn’t terribly good at it but I played because I was very interested—it’s a scientific game. There’s a lot of strategy involved. Again, though, it’s a team game. Interview But science is a combination of individual and team sport. Absolutely. I think that the individual part of science is to get the inspiration. You have to be a bit of a loner to explore the ideas or learn how you might apply them. That means library work, it means thinking. It means being on your own. Of course you might be inspired by other people that you work with but you have to come up with your own ideas. Once you’re in a group of people that you have to depend on to explore these ideas further, it becomes teamwork. You have to also be a good team player. sented. In America you could make a mistake and correct it. You could make a mistake in your career, have a setback in your business, and you could still recover from it. You started your graduate work on mass spectrometry at Liverpool in 1966. What appealed to you about the technique? It was the fact that you could take such a tiny amount of material, put it in the machine and learn so much about it. In less than five minutes you would generate enough information to give you a lot more structural knowledge. Why was it so difficult? By that time there was a glut of chemists and the opportunities were few and far between. How would you describe the essential principle of the approach? In a nutshell, mass spectrometry gives you massmolecular weight, and structural information, with almost no work. One of the things I find very fascinating about mass spectrometry is the pace of development that’s enabled us to go from small molecules, like steroids—which Nobel prizes were won on—to mediumsized molecules, to macromolecules all in the space of 15 to 20 years. It’s absolutely astonishing. You were in on the ground level. What were you learning about your own strengths and weaknesses as a scientist? I wouldn’t describe myself as a great scientist. I did not have a good pair of hands in the lab, for example. I was not a great chemist. There are some people who have the patience and ability. Laboratory science, especially chemistry, is a bit like a black art in some ways. Or like a green thumb in gardening. Yes, you’re either good at it or you’re sort of average. You can get results but you’re not brilliant, that was me. I could follow instructions—I could do certain things— but that was not my forte. That’s another reason why I like mass spectrometry. It’s looking at molecules in an isolated environment out of the lab. A whole different chemistry goes on there than in solutions where you’re mixing things together in the test tube. You came to the University of Illinois at Champagne Urbana after finishing your thesis. How did you like life in the States? What we loved was the friendliness of the people, the openness, the space, and the opportunities that were pre- You came with your wife. Where did you meet her? I met my first wife locally—she came from a town called Darwen in Lancashire. I asked her if she would marry me and come to America. We didn’t have children yet. Then I went back to the UK. I couldn’t get a job. We couldn’t start a family until I felt like I had a job. It was challenging. You decided to do a post doc at University College Cardiff and stayed on for a lectureship at Tenovus Institute for Cancer Research. My predecessor there was a physicist. It was thought at the time that physicists should be in control of mass spectrometers. This particular physicist realized that it really needed a chemist to run this thing. So he contacted me. I got the position. The mass spectrometer at Tenovus was one of only two of its type in the country. It came from Germany—it was very high end. I was almost afraid of it. It was such an expensive and large piece of equipment. I decided that I didn’t know enough about the mass spectrometer’s insides, the guts of the machines. I needed to know more and that’s what drew me into industry. You took an appointment in industry in 1976. This company that I joined was a mass spectrometry company—their mission was to make and sell and develop technologies around mass spectrometry. It was one of the few companies that actually built mass spectrometers from scratch. Was your work fruitful? It was. I was applications manager and my job was to expose potential clients to these instruments and help them to solve their problems. The field was changing and expanding and new technologies were being developed all the time. I could name ten or more really significant advances that I saw while I was in that company. If you left to go on vacation and came back there would be something new to see. Lots of very good scientists were there working in those companies—they were true pioneers. If a client was interested I would be the person who would entertain them, take them to dinner, and lunch, talk to them about their application. Of course, they always brought the most challenging problems. It was a very difficult job—probably the most difficult job I ever did. But it was very rewarding. After five years of that— and there were some upheavals from a management point Clinical Chemistry 62:1 (2016) 15 Interview of view—I decided that I should get out of that environment and back into academia. In 1981 you spent a few months as a visiting professor at the University of North Carolina (UNC) at Chapel Hill. How did that come about? I was a very frequent visitor to the US and came to know many scientists in both industry and academia. I had started to ask colleagues over here if they knew a place that I might fit in. One of them suggested UNC because they had just bought a new mass spectrometer from the company that I worked for. They thought I could help them establish a basis for that machine, to teach the faculty how to make effective use of it. How did you come to Duke? I was introduced to a professor at Duke who had knowledge of mass spectrometry. He was one of the few people in North Carolina who had a gas chromatograph–mass spectrometer. He had done some training in the UK and learned the applications of mass spectrometry to solve problems with metabolism. Was this Charles Roe? Yes. He wanted to analyze a group of compounds that I had never heard of before. This was a medical science opportunity that appealed to me. He came to you with a specific case of a child with a metabolic disorder. That’s absolutely right. I was seduced by the whole story. This was a child with propionic acidemia. It’s one of those inherited metabolic diseases that was very difficult and challenging to diagnose at the time. You need a gas chromatograph–mass spectrometer to do it and he had one. He diagnosed the child, who unfortunately had a very bad course. It was a devastating disease. In those days you weren’t expected to survive into early childhood with that condition. He had a theory about it and he wanted to explore that theory. From what I gleaned, in an effort to save the boy, Roe had given him a dose of L-carnitine, which led to his theory that L-carnitine is a detoxifying agent. Is that correct? What L-carnitine does is help transport fatty acids into the mitochondria, the powerhouses of the cell. In addition it can help to get abnormal species out of the mitochondria. One of these abnormal species is called propionyl-CoA—it’s a cytotoxic agent. Carnitine can combine with it and get it out of the cell and thereby free up the metabolism again. The theory was that it should be able to do that, but no one had actually had the guts to give it to a patient. What I heard is that the child was about to 16 Clinical Chemistry 62:1 (2016) expire and this was a last ditch effort to save his life. The last rites had been given. So when Dr. Roe gave him this and it revived him—Dr. Roe tells the story that the kid was sitting up, laughing at everyone within four hours of giving the drug. They thought, “Oh it’s a miracle.” That’s a dramatic story! When I heard it for the first time, I was captivated. Then he said to me, “I have this mass spectrometer. Can I analyze these compounds with it?” I said, “You can’t. You need something more sophisticated.” That’s when we got into the conversation about tandem mass spectrometry and its application. Was that the challenge that led you to tandem mass spectrometry? I already had exposure to tandem mass spectrometry in the company. I’d already developed applications and published some of them, again with colleagues in academia. You had been pairing mass spectrometry with gas chromatography and liquid chromatography to break analytes into components. Does the second mass spectrometer take the place of the gas chromatography– liquid chromatography? If you like, yes. When you have a mixture, some of them are so complicated you can’t analyze them at one go. What the tandem mass spectrometer does is to ionize the mixture components that you put in without breaking them apart. In other words, it uses a “soft” ionization technique, which means that instead of breaking the molecules apart they stay intact. Then one by one, according to the mass-to-charge ratio, you introduce them to the second part of the mass spectrometer, where they are broken apart and give you the structural information. Why would anyone use anything but tandem mass spectrometry? Why use gas or liquid chromatography? You still often need an extra separating component because you’re looking into the details, the small stuff that we don’t normally see. To get into that depth of analysis you may still need to have separation prior to the mass spectrometry. How did you apply tandem mass spectrometry to the case of the child? During our first meeting, Dr. Roe had something that was sticking out of his shirt pocket. It turned out to be a test tube. Eventually he pulled it out and showed me—this was part of the seduction, I’m sure. There was a dry powder in the bottom of it. He said that was the freeze-dried urine from this child after the carnitine had been given. He wanted me to figure out how to analyze that material for the propionyl carnitine, Interview which he was expecting to find there. Using the tandem mass spectrometer, we were able to detect a signal in the mixture of urine that had the correct molecular weight for propionyl carnitine. We were able to analyze the structure of that and show that it was the same as the pure material [propionyl carnitine] that we had made earlier in the lab. You ended up leaving UNC and moving to Duke to work with Charles Roe. How did that happen? The reason I got into the work with Dr. Roe in the first place is because I knew something about it—I’d worked with this company that had developed those techniques. I knew there was a solution to this problem that Dr. Roe had. That’s serendipity— him being interested and maverick enough to actually try the therapy out and me having the knowledge to give him. He eventually said, “Well, look, you must come and work for me.” I’ve spoken with other scientists who have emphasized the role of serendipity in their scientific careers. In my case, it was all to do with serendipity! I had a perfectly good career in environmental chemistry going at UNC. I watched Michael Jordan play basketball there—I was obviously a UNC guy. You’d have to convince me to come over to Duke. Now you’re eternally grateful! I made the decision because of the excitement that was brewing in his mind about what you could do with this technology. There was no tandem mass spectrometry at that time in the clinical diagnostics labs. They were notoriously conservative. It needed someone like Charlie Roe to break the mold. A big turning point in your career was your decision to introduce tandem mass spectrometry into newborn screening. How did that come about? Dr. Steven Kahler came with me from UNC. Dr. Roe hired him at the same time that he hired me. He came as a clinician but he was also by chance on the board of advisors to the newborn screening lab for the state of North Carolina. We had established a clinical diagnostic test for a group of metabolic disorders, which didn’t exist before, that became known as the acyl carnitine profile. We were applying tandem mass spectrometry to accomplish this, first on urine and then we figured out how to do it on plasma. Dr. Kahler came to me one day and said, “Have you ever thought of trying this technique on dried blood spots?” I didn’t know what a dried blood spot was. He educated me. The idea was crystallized that we should retrieve newborn dried bloods spots from patients that had been diagnosed, at Duke, with inborn errors of metabolism within the last five years; who were still alive; and for whom we could ask the parents’ permission to get David Millington and Charlie Roe these cards. We were then able to show by retrospective analysis of those spots that we could’ve diagnosed them at birth had we had the opportunity. That’s what got us into the business of newborn screening. Was it a technological challenge or was it simply applying what you’d been doing before to this new kind of sample? We had to learn how to manipulate the dried blood spot. It turned out to be relatively straightforward and, to our amazement, we could see all the same signals that we were seeing in the plasma of the same patients when they were in the diagnostic lab. What were the next steps? What we’re talking about is public health. We needed the right spirit at the newborn screening lab in North Carolina, and they had it. That generosity of spirit allowed us to collaborate with them—they actually funded part of the project. The money was used to help drive the new technology to apply it to large numbers of samples. The population of newborns in North Carolina is 120,000 a year. That’s a lot of samples for a technology like this. You need high throughput and that was what the money was for. At what point did you know that this was a successful approach? To be honest, we were trying to develop a method that was going to become obsolete within a couple of years, without us realizing it. A new technology called electrospray was being developed. It was much easier to analyze samples on the fly one after the other in sucClinical Chemistry 62:1 (2016) 17 Interview cession with electrospray than it was with the method that we had, which was fast atom bombardment. Nevertheless, we were publishing papers through the 1990s and other laboratories across the world were starting to use our technology in newborn screening labs in Australia, South America, and Saudi Arabia and elsewhere. The 1990s were a defining period for you. Most people in my position would’ve published a couple of papers and then walked away from it— gone on to the next thing. I had to make a commitment to this because of the importance of it and the fact that we had to keep pressing to get over the barrier of resistance. You need powers of persuasion to get through the layers of bureaucracy to start his process. That’s what I decided to do, to spend a lot of time doing that and educating people. You were probably working around the clock. What was happening with your family? When I came to take the job at UNC—at first it was temporary and later a permanent position—I brought my wife and two small children, a son and a daughter. That first experience was just a look-see: is this going to be an experience we’d like to do together? It was a universal “yes” from all of them. That’s why I decided to apply for the position at UNC. That was around 1979 –1980. So my daughter would be 7, my son 5 when we came. Did they turn from British children into American children? My daughter was able to switch her accent when we went to England—it was quite interesting to see that— but she gradually became more American than British. My son went to school here from when he was 5 years old so he’s pretty much Americanized. Back to newborn screening, is it implemented in every state? Oh yes. But it took until 2008 for all of them to come on board. This has saved and improved many lives. Is there any estimate of how many diagnoses are made every year that would otherwise have been lost? I don’t keep track but I know that in this country we have at least four million newborn births annually. We’ve now been doing this since 1997. If you think about all the babies that have been screened in this country, that’s probably approaching 50 million, if not more. Then worldwide, you’ve got Australia, New Zealand, Canada, Mexico, South America; almost all of the countries in northern Europe. England, Germany, Switzerland, Aus18 Clinical Chemistry 62:1 (2016) tria, Italy—they’re all doing newborn screening by this method. That must make you feel amazing! I tell you what it’s done for me, what I see as its main contribution. It’s put newborn screening on the map. It’s done more to promote an awareness of how it can save lives than I could’ve possibly imagined. It’s become like a mission for me to pass on the knowledge. I could’ve easily gone off in another direction and become an expert in protein chemistry—that’s where I started. Protein chemistry has been revolutionized by mass spectrometry. I chose to stay with small molecules in this area because I thought it could make a bigger impact. You’ve written about new approaches to newborn screening such as digital microfluidics that could address some of the limitations of tandem mass spectrometry. Tandem mass spectrometry is right now having its best years but something will supersede it. There’s talk about genetic screening, which is actually becoming feasible from a dried blood spot. Imagine that every single known mutation that causes disease could be screened from one dried blood spot. That is likely to happen whether we want it to or not. Where I’m coming from with resources like digital microfluidics is if you keep taking dried blood spots from babies, sooner or later you’re going to run out of material. If you miniaturize everything down to droplet level, then you’re able to do several analyses that normally wouldn’t be possible with a mass spectrometer. I’m a techno-geek—I love technology. I see something and I think, “That could be useful.” You don’t sound like someone who is retiring. You’re so engaged and involved. Why are you retiring? I’m retired from the nitty-gritty of being full time lab director—that’s a very time-consuming job. That’s true—you’re responsible for analyzing thousands of samples. And reporting on them. Also, as a faculty member you have other responsibilities. Showing up for work to do that routine stuff everyday—I’m 71 years old, 72 is coming up—I have to admit it’s getting tiresome. I hope to stay working on the education side of newborn screening. I hope to stay involved with digital microfluidics as a consultant or advisor. Have you heard the expression “Old professors never die, they merely lose their faculties”? That’s maybe what’s happening. I’m going to lose my faculties but I’ll still be able to contribute where there’s an opportunity and a need. I like traveling—my wife and I will do some traveling, see some of the things that we haven’t had time to visit. Interview Anything else? Playing more golf with my son. I’ve been out of golf for a long time so I’m going to start practicing again. I’m still fit enough that I can enjoy that. I like to do projects around the house. I’m sure my wife has a ‘honey-do’ list that’s a mile long. I haven’t seen it yet but I know that she’s got one. I asked you earlier whether your kids had turned into Americans. What about you—are you still British? I’m both. My wife too. I guess we have to say we’re Americans first because this is our home. We chose to live here. We’ve had a really, really good experience in North Carolina, especially the Chapel Hill Research Triangle area. Our family in the UK also mean a lot to us. We want to be able to go back to visit and see some of the things in the UK that we have not seen. We’ve seen Grand Canyon, Yosemite, Yellowstone, Mesa Verde—we’ve probably seen more of the wonders of America than most Americans will ever see. Now we’re going to go into Europe and do what we missed and failed to do when we lived there. I’d like to end with a quote from Harry Hannon, who is chief emeritus of the newborn screening and molecular branch of the Centers for Disease Con- trol and Prevention. He said, “Newborn screening creates a passion that drives people to put in much more than 40 hours a week. You can see the impact of your work immediately.” That must resonate with you. Definitely. Those of us who are in newborn screening, we’re not in it for the money—we want to do it because we know it makes a difference in people’s lives. Are you still passionate? Yes. As long as I can be useful, I’ll continue doing it. The opportunity that this has created for me has been wonderful. I’ve been very lucky. To still be healthy enough to do all this, and enjoy doing it, is a blessing. Many of us are not that fortunate. You have to have a lot of luck—that’s true both in life and in science.
