Institute for Pure and Applied Physical Sciences (1980-1991).

One of Harry Suhl's most endearing qualities is his sense of humor. At Bell Laboratories and La Jolla, he is
famous for his dry wit and, especially, his 'one liners'. Here are just a few examples.
In the late 70's, Harry and one of the UCSD Physics professors shared a secretary by the name of Julie. We heard about
something called "Secretary's Day" and decided to invite Julie for lunch at a local restaurant, the Marine
Room, which is located just south of Scripps Institution of Oceanography and has a spectacular view of the
Pacific Ocean. On the day of the lunch, the three of us get into the front seat of Harry's Cadillac Eldorado
(Harry has a penchant for Cadillacs - we don't remember him having any other kind of car). As we were
driving along, Julie, who was sitting in between us, looked over and said "Dr. Maple, how far are you jogging
these days?" This yielded the answer "Oh, about 12 miles a week" (a distance appropriately inflated to
impress). She then turned to Harry and inquired "Well, Dr. Suhl, what do you do for exercise?" Harry replied
"Oh, I really don't subscribe to strenuous exercise; however, I do get up every morning and wind my watch
by an open window."

Although he seldom followed his own advice, Harry was once heard to declare "Everything should be taken
in moderation, including moderation'" In the 60's when Harry and many of the new faculty at UCSD were
designing and building their houses, he told John Goodkind: "...Everyone should build a house in his own bad
taste." When a young Assistant Professor expressed some concern about his prospects for attaining tenure at
UCSD and asked what he should do, Harry responded "Speak only when spoken to, and then give only your
name, rank and serial number!" Sometime in the 70's, a number of us were having lunch at the Coffee Hut,
located in a grove of Eucalyptus trees on the southwest part of the UCSD campus, and complaining about our
income taxes. Harry exclaimed that he had just discovered a new theorem: "The area over all of the tax 'loop
holes' is constant." On another occasion at the Coffee Hut, several of us were discussing our teaching reviews
that had just appeared in a student published booklet called CAPE (Course and Professor Evaluations). Harry,
who is meticulous in his dress, was particularly proud of the following comment made by an undergraduate:
"This was not a very interesting course, but the Prof's a snappy dresser!"

At the Conference Banquet, Professor Phillip Anderson of Princeton University, one of Harry's old friends
and colleagues from the Bell Labs days; reminisced about the 'old times' and described some of Harry's
research accomplishments. A number of other colleagues and friends also made brief remarks. Harry's
response, which reflects his usual charm and sense of humor, is given below.

"It is not easy for me to convey to you my appreciation for honoring me in this fashion. As I was saying to
Dean Attiyeh, when he congratulated me yesterday, I am particularly appreciative of this honor, because it is
probably undeserved. You see, if it were fully deserved, I would be able to say: well, I had it coming. But as it
is, I feel I am getting something for nothing, and that is always a pleasurable sensation. The reason why I feel
somewhat undeserving is because I have always taken a rather hedonistic view of physics, in that I have
worked on the urgent and burning problems of the day if and only if I found them to be amusing. Perhaps
that is no way to maximize your fame and fortune, but it sure is a lot of fun.

By the time you are seventy years old, you are supposed to have learned a few things. Furthermore, you are
supposed to communicate the essence of what you have learned to your younger associates, whether they
want to hear it or not. So here are a few gems that I have extracted from my long years in our profession.
First of all. I found that the notion that people become less productive with advancing years is probably
not correct. They don't usually become less productive, they just become less relevant, present company
always excepted, of course. In fact, they become better and better at what they do, but fewer and fewer people
want to hear about it. Like aging cabaret dancers, they become like Antarctica: Everybody knows about it,
but nobody wants to go there.

Secondly, and more seriously, I found that. in theoretical physics at least, the young people who have been
coming out of school during the last fifteen or twenty years are much better trained in mathematical
techniques than we were in my own youth. I am very puzzled by this, because their teachers were more or less
of my own generation, so I don't see how they could have converted their students into such power houses of
mathematical techniques. I can only conclude that these youngsters must have worked very hard to educate
themselves, or must have been very brilliant. In either case, if my conclusion is correct, then we should pay
them a great deal of respect, even if they make us feel stupid.

Another thing I have learned about our young colleagues is this: there are certain problems in theoretical
physics that are well-known to be insoluble. Unaware of this, these brash youngsters go ahead and eventually
solve them anyway, one way or the other. If they can't solve them in a head-on attack, they find ways to go
around them. Unburdened by the wisdom of age, they plough ahead anyway. This leads me directly into my
next task, that of giving some totally unwelcome advice to the younger people: Above all, don't get wiser as
you get older. If you do, you will become too inhibited to try the impossible. and one can achieve the limits of
the possible only by occasionally venturing beyond these limits. The famous proverb should really be
transposed. It should read: Angels rush in where fools fear to tread.

Secondly, if you publish something, and they don't believe you right away, say to hell with it and go on to
the next thing. That sounds downright immoral, but I don't think it is. I remember that Hitler used to
frequently say: History will decide. And, as it turned out. he was right, at least in his own case.
Finally, always work on good ideas, rather than on your own ideas. If I had followed this advice myself,
instead of narcissistically pursuing my own thing, I would by now have become even more insufferable than
I already am.

Speaking of insufferable, I think it is time to wind down with a couple of personal remarks. True, I am
finally getting old, but I now would like to be twenty five or even thirty five years old only if I would know what
I know now. Otherwise, I want no part of it. I think it is true what they say: 'You are young only once, but if
you work it right, once is enough: And I must admit, I harbor the illusion that I have worked it more or less
right.

Be that as it may: I assure you, I will long remember this meeting, and when I finally kick over and get to
the Pearly Gates, I will take with me a list of participants and put in a good word for you. Who knows, as
these controversies on high Tc's, Kondo lattices, and heavy fermions heat up, some of you may need a good
word from me. Thank you all very much."

Suhl's research covers statistical mechanics and critical effects in non-equilibrium systems, magnetism on macroscopic and mesoscopic length scales, reaction kinetics and non-linear dynamics

Dr Suhl's research covers the following areas: statistical mechanics and critical effects in non-equilibrium systems, magnetism on macroscopic and mesoscopic length scales, reaction kinetics and non-linear dynamics.

As an example of the first and second items, we examine the role of self-organized criticality in magnetic domain formation. Currently we examine magnetization reversal processes and magnetic multilayer structures. In reaction kinetics, the research is directed towards finding formulae for rate constants when traditional rate theory fails.

In non-linear dynamics, we attempt to determine the kind of states in which complex systems settle down, starting from unstable configurations.

Harry Suhl is a German-anmerican physicist. He  was born in Leipzig, Germany, on October 18, 1922. He received a B.Sc. degree from the University of Wales in 1943, and a PhD degree in theoretical physics from Oriel College, University of Oxford, in 1948.

In 1948, he joined the technical staff of Bell Telephone Laboratories at Murray Hill, New Jersey, where he remained until, in 1960. he was appointed Professor of Physics at the University of California, San Diego; he became Professor of Physics, Emeritus, in 1991.

Research

With William Shockley in 1948, Suhl contributed to fundamental aspects of charge carried dynamics in semiconductors. In 1953, he and Larry R. Walker developed a detailed analysis of wave propagation in waveguides loaded with gyromagnetic and gyroelectric media, pertaining to certain microwave devices. Suhl gave the definitive explanation of nonlinear effects in ferromagnetic resonance (the Suhl instability) in '55/,56, a subject that has recently proliferated. The principles involved led Suhl to patent a ferromagnetic parametric amplifier in 1956. This work stimulated wide utilization of parametric amplification, in general. In 1957, Suhl, and, independently, T. Nakamura, uncovered a major source of broadening of nuclear magnetic resonance lines in magnetically ordered media (the Suhl-Nakamura interaction).

Between 1957 and 1965, Suhl contributed to certain aspects of superconductivity theory (e.g., the so-called two-band model). In 1965, the and, independently, A.A. Abrikosov, resolved apparent divergences in the calculated properties of dilute magnetic alloys, attributing them to a particular resonance (the Abrikosov- Suhl resonance). In the 1970's and 80's he worked in surface physics and catalysis and studied reaction kinetics, in circumstances in which the traditional Kramers-Eyring approach fails. He continues to lead an active research group, including PhD students, at UCSD.

Awards, Recognition and Published Works

Suhl is a member of the National Academy of Sciences and a Fellow of the American Physical Society. He was awarded a John Simon Guggenheim Fellowship in '68/,69, a Doctor of Science degree from the University of Oxford in 1969, and a National Science Foundation Senior Postdoctoral Fellowship in '70/,71. He received an Alexander von Humboldt Senior Scientist Award in 1991. Suhl has served on the board of editors for the Physical Review ('55-'76) and Solid State Communications ('61-'90), is co-editor of Magnetism, a Treatise on Modern Theory and Materials (with G.T. Rado, Academic Press, New York, S volumes, '63-'72), Superconductivity in d- and f-Band Metals (with M.B. Maple, Academic Press, New York, 1980) and Many Body Phenomena at Surfaces (with D.C. Langreth, Academic Press, New York, 1984). He served as Chairman of the Physics Department of UCSD (1965-1968; 1972-1975) and as Director of the Institute for Pure and Applied Physical Sciences (1980-1991).
