Mined from the notebooks Tuesday, April 23, 2019. Posted Wednesday morning, April 24. Revised and corrected below, Thursday morning, April 25.
Nobel Prize-winning physicist Hans Bethe at the blackboard at Cornell in 1967, around, I’d guess, fifteen years after the young RPI physics major Pop Mannion attended one of Bethe’s seminars. Photo courtesy of the Department of Physics at Cornell University.
“Bethe is an odd figure, large and clumsy with an exceptionally muddy old pair of shoe. He gives the impression of being clever and friendly but rather a caricature of a professor; he was second in command at Los Alamos, so he must be a first-rate organizer as well.” ---from a letter by Freeman Dyson dated September 25, 1947, collected in Dyson’s autobiography in letters, “Maker of Patterns”.
I wonder if Pop Mannion would have recognized Freeman Dyson’s description of the great Nobel Prize-winning physicist Hans Bethe. It’s from a letter Dyson wrote in 1947, when he was a doctoral student at Cornell and Bethe was his professor. That was at least around five but maybe ten or even fifteen years before Pop himself met Bethe.
Pop counted Bethe as one of his teachers. It was a minor point of pride with him. Minor as in he kept it in perspective. Bethe taught at Cornell. Pop earned all three of his degrees---Bachelors, Masters, and Ph.D.---at RPI. But at some point in his career as a student, Pop took a week-long seminar with Bethe. I can’t remember exactly when. My impression has always been it was when he was an undergrad. That would put it in the early 1950s. But it might have been while he was working on his masters. At that point, Pop was running the computer department at GE’s atomic power lab (and, incidentally, managing the department’s softball team to the company championship.) That would put it in the late 50s or early 60s and Pop would have been around thirty years old. I like thinking it was when he was a degreeless student, no more than twenty. It’s hard for me to imagine Pop as a college student. Not because he was “born older” like George Bailey. He was. But that’s not the point. It’s simply that he didn’t tell us many stories about that part of his life that didn’t include the girl he was dating at the time, and Mom Mannion wasn’t in college with him, or the United States Air Force, which had him in its ranks as an ROTC cadet. His post grad career I remember because he worked on his Masters and Ph.D. at night and on weekends when I was a little kid and that meant he often wasn’t at home when we Mannion kids wanted to play with him, he was at class or in the library or lab at RPI, and when he wasn’t there he was working and studying at his desk in his “den”, not to be disturbed. The other thing about his seminar with Bethe I can’t recall is where it was held. Bethe might have visited RPI. He might have visited GE. But I like to imagine Pop went down to Cornell when he was an undergrad because Pop lived at home when as an undergrad and I like picturing him making his first long trip away from home. Like I said, having taken that seminar with Bethe was a minor point of pride for him, and he didn’t crow about it. What he was prouder of---well, vainer about, as much as Pop allowed himself a vanity---was the joke he got of it.
Pop also counted George Gamow as one of his teachers, along with Ralph Alpher, who was a friend and a colleague at GE. Gamow he knew through Alpher. It’s more accurate to describe both as mentors. But it was better for the joke to call them his teachers. Here’s the joke:
Pop liked to tell people the list of his physics teachers was so long it ran the whole twenty-four letters of the Greek alphabet, starting with Alpher, Bethe, Gamow.
His jokes were usually funnier than that.
He was proud of the joke, but he wasn’t satisfied with it. It bothered him that he didn’t have any famous professors whose names could be used for a pun on Omega.
Think about it.
I took my copy of “Maker of Patterns”, Freeman Dyson’s “autobiography through letters” with us on our trip up to the Old Mannion Homestead to celebrate Easter with Mom Mannion and various friends and relations. I’d have taken it up to show him if he was still with us, expecting of course that he already owned it himself. “Maker of Patterns” would have been a perfect gift for his birthday, which is coming up on Saturday. That’s why I’m convinced he’d have owned it already. Pop had a habit of buying himself books that would have been perfect birthday, Christmas, or Father’s Day presents for him. It was frustrating. But he didn’t do it to be perverse. He bought books for himself regularly---too regularly in the opinion of Mom Mannion, who had to find a place for them all. If it was left to Pop they’d have piled up in the living room to the point that eventually they have walled him in in his favorite reading chair and eventually one of the towers would have toppled and crushed him where he sat reading his newest acquisition. It was one of his indulgences, of which, like his vanities, he allowed himself few. But if, wonder of wonders, on the off-chance he didn’t already own it, I’d have gotten a kick out of showing him the series of letters Dyson wrote to his family in the late 1940s when he was a doctoral student at Cornell and Bethe was not only his teacher but the head of his dissertation committee. And I’m sure Pop would have especially enjoyed this story, because it includes as a character another physicist he greatly admired:
Dyson writes:
The event of last week has been a visit from [Rudolf Peierls, an old physicist friend of Bethe’s who’d, at about the same time as Bethe, escaped Hitler’s Germany to England where he’d become one of the leaders of the British nuclear bomb project] who has been over here on government business and stayed two nights with the Bethes before flying home. He gave a formal lecture on Monday about his own work, and has been spending the rest of the time in long discussions with Bethe and the rest of us, at which I learn a great deal. On Monday night the Bethes gave a party in his honour, to which most of the young theoreticians were invited. When we arrived we were introduced to Henry Bethe, who is now five years old, but he was not at all impressed. The only thing he would say was “I want Dick. You told me Dick was coming, and finally he had to be sent to bed, since Dick...did not materialise. About half an hour later [Dick] burst into the room just had time to say “so sorry I’m late. Had a brilliant idea just as I was coming over,” and then dashed upstairs to console Henry. Conversation then ceased while the company listened to the joyful sounds above, sometimes taking the form of a duet and sometimes of a one-man percussion band.
The one-man percussion band was---you guessed it---Richard Feynman.

It’s possible Pop met Feynman at Cornell. Barely possible. But only if Pop took that seminar with Bethe at Cornell and when he was a freshman at RPI. Feynman left Cornell in 1951. Fact is, however, I’m pretty sure he never met Feynman. He’d have never stopped talking about it if he had. It would have been more than a minor point of pride for him and he wouldn’t have cared if he got a good joke out of it. Feynman was one of his heroes.
So he’d have enjoyed this from Dyson’s letter home, dated November 19, 1947:
“Just a brief letter before we go off to Rochester [New York, about a two-hour drive from Ithaca]. We have every Wednesday a seminar at which somebody talks about some item of research, and from time to time this is made a joint seminar with Rochester University. I am being taken in Feynman’s car, which will be great fun if we survive. Feynman is a man for whom I am developing a considerable admiration; he is the brightest of the young theoreticians here and is the first example I have met of that rare species, the native American scientist. He has developed a private version of the quantum theory, which is generally agreed to be a good piece of work and may be more helpful than the orthodox version for some problems. He is always sizzling with new ideas, most of which are more spectacular than helpful and hardly any of which get very far before some newer inspiration eclipses them. His most valuable contribution to physics is as a sustainer of morale; when he bursts into the room with his latest brain wave and proceeds to expound it with lavish sound effects and waving about of the arms, life at least is not dull.”

Updated and corrected Thursday morning, April 25, 2019 because DAMMIT! there are holes in my memory that need to be plugged: The Alpher, Bethe, Gamow joke wasn't Pop's. He appropriated it---from Gamow. Gamow wrote a seminal paper on the Big Bang with Alpher, who was his doctoral student at George Washington University, and he added his friend Bethe's name so that it would always be cited as Alpher-Bethe-Gamow. The paper was published in 1948, when Pop was in high school. But Pop read it, although probably not when it was published, and of course understood it and appreciated its ramifications, as well as getting a big kick out of the joke, which he told me about and explained to me when I was just out of grad school and reading Richard Rhodes' "The Making of the Atomic Bomb", one of my and Pop's favorite books. I'd asked him in he'd met any of the physicists mentioned in the book. That's when he told me about taking the seminar with Bethe and about the paper and the joke and his connections to Alpher and Gamow and how he liked to tell people about the paper, the joke, and how the joke could be applied to his own resume. Pop never took credit for somebody else's work or their jokes.
As it happens, Pop's connection to the Manhattan Project and the making of the atomic bomb and probably initially to Bethe was through his boss as GE, Richard Ehrlich, known to Pop and Mom Mannion as their good friend Dick but to us Mannion kids as Dr Ehrlich and someone we had to be on our best behavior around when he visited our house, although I remember him as a kindly, avuncular, and always broadly smiling man. Dr Ehrlich had worked under Bethe at Los Alamos, amd since Dr Ehrlich and Mrs Ehrlich were regular dinner guests at the Mannion Homestead, I can claim one degree of separation form the bomb dropped on Nagasaki and isn't that special? But it makes it likely that Pop took that seminar from Bethe when he was working at GE and not when he was a student and that it was held in Schenectady. One other thing about Dr Ehrlich. His influence on Pop was political as much as professional. He was the chair of the local Democratic committee when we moved to Niskayuna and he recruited Pop to run for town board. Pop got skunked that time out. But he learned valuable lessons that he put to work when he ran for supervisor a few years later.
All this came back in a rush last night when Mannionville stalwarts Joel Hanes and Kaleburg reminded me in the comments here and Facebook pal Neil Calkin reminded me over there about Alpher-Bethe-Gamow. Thanks, old chums, for calling attention to the paper and to my incipient senility.

“Maker of Patterns: An Autobiograhy Through Letters” by Freeman Dyson is available in hardcover and for kindle at Amazon.
Another of Pop Mannion's favorite books by about science was Gamow's "One Two Three...Infinity". He cherished his first edition copy all his adult life. It was published when Pop was in high school so it may have been the first adult science book he owned. His affection for it wasn't just nostalgic either. He thought it was a classic of its kind and recommended to everyone as the best introduction to scientific and mathematical thinking about how the world works. He might have known this, but if he didn't it would have done is heart good to find out it's still in print. "One Two Three...Infinity" is available in paperback and for kindle at Amazon.
Pop would also recommend Feynman's "What Do You Care What Other People Think?"
You don't mention it, so I'd be remiss if I didn't provide a reference to the famous story about a much-cited paper in physics. Alpher and Gamow collaborated on the research, on the nucleosynthesis of elements in the cores of stars, and when it came time to publish, Gamow added Bethe (who IIRC knew nothing about this shenanigan) to the list of authors, so that the official cite is Alpher, Bethe, Gamow.

So your Pop was citing Gamow's famous joke.

The Alpher-Bethe-Gamow paper was the first to present the big-bang theory of the origin of the universe. The story is that Alpher and Gamow recruited Bethe as the missing letter.

That looks like a good read! I attended a Bethe lecture I am proud to say. It was one of the few times my Dad took me to something special so its also a fond memory for me. Hans Bethe was working at the GE Lab for a short stint and he was giving a general lecture to the whole assembly in the auditorium. My Dad kept leaning in as Bethe spoke telling me how he had advanced our understanding atomic structure. As I recall he was a very mild speaker his manner was not overbearing yet he had the whole room.
