EDWARD UHLER CONDON
March 2,1902-March 26,1974
BY PHILIP M. MORSE
THE MIDDLE THIRD of the twentieth century was the era of he-
gemony of physics in American science. During that period
Edward Uhler Condon was a leader in physics, in research of
his own, in stimulating research in others, in applying physics,
and in calling attention to the effects on all of us of its indis-
criminate and irrational application. When he made his first
contribution to theoretical physics in 1926, the word physics
was not in the vocabularies of most Americans and the revolu-
tionary concepts of quantum mechanics and relativity were just
being worked out in Europe; by 1960 the applications of elec-
tronics and solid-state physics had begun to change our lives
irreversibly, and the implications of nuclear physics were mani-
fest to everyone. Ed Condon contributed to each part of this
explosive evolution.
Condon's father, William Edward Condon, was a builder of
railroads in the West. He and his wife, Carolyn Uhler Condon,
moved from place to place as the construction jobs required.
When Ed was born, on March 2, 1902, they happened to be in
Alamogordo, New Mexico, an ironic coincidence not apparent
until July 16, 1945. By the time he was ready for high school,
the family had settled down in Oakland, California. Ed's rival
interests, science ant! journalism, pulled him in different direc-
tions. In the turbulent year of 1918, when he graduated, rather

than going on to college he became a reporter for the Oakland
Enquirer. His experience in the ensuing three years had a last-
ing effect on his attitude toward government and society.
In his own words, "On the Inquirer I specialized in the news
of organized labor.... The dock workers, the timber workers,
and the migratory farm laborers .... ~ v
The California state legislature had passed a strong bill defining
criminal syndicalism and making it a felony. The politicians
were looking for a place to use it. On November 9, 1919, I was
the only reporter from a conservative newspaper to cover the
organization meeting of the Communist Labor Party of Cali-
fornia, as it was called then. I wrote lurid and sensational stories
about this small group of one or two hundred persons, which
resulted in indictments against them, and which required that
I had to testify against them, in trial after trial, over the next
several years. In this connection I became aware of open boast-
ing by a police detective of his having framed some of the
defendants in a matter where I knew the facts to be otherwise.
The effect of this involvement on me was to wipe out any desire
to be even an educated newspaperman; so I entered the univer-
sity and went into physical science largely as a means of escape
from the corruption of the world, in addition to the fact that I
was genuinely interested in physical science."
He entered as a freshman in the College of Chemistry of the
University of California at Berkeley in 1921, but when he
learned that his high school physics teacher, W. H. Williams,
had joined the physics faculty at Berkeley he switched from
chemistry to take Williams's courses in theoretical physics; thus
his choice of career was determined. In that same year, 1922,
he married Emilie Honzig, a tiny bundle of energy who en-
were rlrnwn to communism.

couraged Ed in his scientific work and actively supported his
. . . . .
extracurricular actlvltles.
At that time, as Condon has commented, "The physics
department was comparatively weak in a research way, except
for the recent addition to the faculty of R. T. Birge, who
concentrated on the early development of the quantum theory
interpretation of diatomic molecular band spectra, and of
Leonard B. Loeb, who has spent a lifetime making important
contributions to processes of ionization in gamest
Ed did well, for he received his A.B. degree in three years
with highest honors, went on directly to graduate work in
physics, and received his Ph.D. in 1926. Birge was then making
great progress in measuring and analyzing band spectral intensi-
ties. Condon put these observations together with a suggestion
of James Franck concerning the photodisintegration of diatomic
molecules to come up with an explanation of the regularities in
the intensities. He wrote it up over a couple of weekends and
presented it to Birge as his Ph.D. thesis. The combined
suggestion-explanation became known as the Franck-Condon
principle, after Condon reworked it later, in the language of the
newer quantum mechanics.
In those years an education in physics was not complete
without a year or two spent in Germany. Condon received a
National Research Council fellowship and he and Emilie, with
infant Marie (now Mrs. Wayne Thornton, fir.), spent the fall
of 1926 in Gottingen and the spring of 1927 in Munich. He
imbibed the probabilistic interpretation of quantum mechanics
from Max Born and, under Arnold Sommerfeld, began the
wave mechanical formulation of the Franck-Condon principle.
Again the rivalry of interest between the gaining and the
imparting of new knowledge intervened. Quoting Condon
again, "By spring and summer of 1927, papers in quantum

mechanics were appearing at a great rate. In those days a young
theoretical physicist was supposed to keep abreast of progress
in every area of theoretical physics. I became discouraged and
decided that if this were the normal pace of work in my chosen
field (which it was not!) then I was not equal to the task. About
this time there appeared a help-wanted advertisement in the
Physical Review for a man to write popular science for an
industrial laboratory, the requirement being stated that the
candidate must have newspaper writing experience as well as a
Ph.D. in physics. I may well have been the only person in
America with that combination at the time. At any rate I
applied for the position, was interviewed for it in London, and
accepted it. It turned out that the position was in the public
relations department of the Bell Telephone Laboratories, then
in its old quarters at 463 West Street along the Hudson River
in lower Manhattan.
"We returned to America and found an apartment near
Columbia in October 1927.... At Bell Laboratories, C..~.
Davisson and L. H. Germer had just done the experimental
work on scattering of low-energy electrons by single crystals of
nickel which led to one mode of discovery of electron diffrac-
tion.... The importance of this work was not at first appreci-
ated in the business management side of the Bell Labs, and I
devoted a good deal of attention in the fall of 1927 to explaining
to such people that the work was destined to win for the Bell
Labs the first Nobel prize to be awarded to an industrial
. .
Organization....
"In that fall I soon found that the American physicists on
the Atlantic Coast were by and large having as much trouble
understanding and assimilating quantum mechanics as I had
had in Germany.... The profession of theoretical physics was
much smaller then than now. As I remember it, Gregory Breit,
John Slater, John Van Vleck, and Edwin Kemble were about
the only ones in America who were really active in research in

I soon found myself in demand as a
colloquium speaker at various universities . . . and King en-
couraged me to accept such invitations, even though they bore
little if any relation to the work I was supposed to be doing for
the telephone company.
"I was asked by George Pegram to be a lecturer in physics at
Columbia University in the spring of 1928.... I accepted and
started on my first regular university appointment by giving
two graduate courses, one in quantum mechanics and the other
on electromagnetic theory of light.... Besides giving these
courses I traveled around giving colloquium talks on quantum
mechanics and also on the Franck-Condon principle. So great
was the demand for young faculty who could deal with these
subjects that in the spring I was offered six assistant professor-
ships for the fall of 1929.... I ended up by taking the offer
from Karl Compton to go to Princeton...."
The chronicler of this biography first met Condon at Prince-
ton in the fall of 1928. He was a new kind of professor. A close-
cropped brush of black hair accentuated the roundness of his
head, his broad face was usually adorned with a grin, and his
brown eyes looked steadily but somewhat skeptically at one
through rimless glasses. The western vocabulary, the proletarian
outlook, the rough-edged kindliness—all contrasted with the
eastern establishment manners that were then the Princeton
norm. He was only a year older than the chronicler, but while
his greater experience and maturity made a great deal of differ-
ence to the student, it made no difference to the professor.
Condon has remarked that this first year at Princeton, 1928-
1929, was the most productive in his life. He has said, "For
teaching I gave a course in quantum mechanics again, improv-
ing the notes of the previous Columbia course, and a junior
course in classical mechanics of which the most outstanding

student was E. Bright Wilson . . . now Mallincrodt professor of
chemistry at Harvard. Philip M. Morse, who had received a
doctorate under K. T. Compton, . . . took my course and we
worked up the lecture notes into the book Quantum Mechanics
(Condon and Morse), which was published by McGraw-Hill in
the fall of 1929....
"I personally wrote the paper which gave a fuller statement
of the quantum mechanics of the Franck-Condon principle....
By far the most important piece of work done that year was the
development of the barrier leakage picture of alpha-particle
radioactivity, done with R. W. Gurney. The same idea was
developed almost simultaneously by George Gamow, then a
postdoctoral fellow in Gottingen. This was the first application
of quantum mechanics to details of inner structure of atomic
nuclei, and at the same time its success gave a big boost to the
probability interpretation of the intensity of the Schrodinger
wave which was only being reluctantly accepted in some
quarters." ~
Condon still was footloose. He accepted an offer of full
professorship at the University of Minnesota for the fall of
1929. But within a year he decided he preferred the stimulation
of congenial colleagues to the kudos of the full professorship,
so after giving summer courses at Stanford, he returned to
Princeton in 1930, where he remained until 1937. During that
decade he began to show his ability to spot, energize, and guide
emerging leaders in the next generation of theoretical physicists.
Two of them have reported how he did it.
George Shortley, who became professor of physics at Ohio
State University and went into the field of operations research
during and after World War II, writes: "I was a senior at the
University of Minnesota, taking a physics minor in my electrical

engineering program. I signed up for both of his courses. His
appearance was quite different from that of any professor I had
ever seen. He was jovial, chubby, black-haired, crew-cut
and
boyish in appearance, wearing cream-colored plus-fours, after
the fashion of the day for students, but decidedly not for faculty.
One of his courses was the theory of atomic spectra, taught in
the quantum-mechanical technique of Dirac before any use-
able text was available. The other was a course in classical
methods of mathematical physics. The two courses meshed
perfectly because the same mathematical functions were used
in both. Condon was a beautiful lecturer; he had the facility of
'making a difficult subject sound easy' whereas other professors
often hacl the opposite tendency to 'make a simple subject
sound difficult.'
"These courses aroused my interest in the theory of atomic
spectra and led eventually to my collaboration with Condon on
the well-known book on this subject. In fact, later in this same
senior year, Condon and I wrote and published our first joint
research paper in this field.
"Early in 1930 Condon decided to leave Minnesota and
return to Princeton. With considerable difficulty he arranged
for me to go with him to Princeton as a graduate student. He
also arranged for me to be his research assistant, at a salary that
would enable me to support myself. After teaching at Stanford
in the summer of 1930, he picked me up in Iowa for the drive
back to Princeton with his wife Emilie and their little child,
Marie, called Madi; in fact Madi sat on my lap for most of the
trip.
"When I reported for my duties as research assistant he
proposed the collaboration on the monograph on atomic spec-
tra, and we proceeded to outline the chapters then and there.
As indicative of the energy he expected of himself and of his
students, he asked me the next morning how much I had writ-

ten. Fortunately I had applied myself the previous afternoon
and evening and had the draft of half the introductory chapter
to show him."
And Frederick Seitz, president of the National Academy of
Sciences from 1962 to 1969 and since then president of Rocke-
feller University, writes: "I was a sophomore at Stanford Uni-
versity and decided to do my bit to reverse negative trends in
society by becoming a professional physicist. While still enjoying
the feeling of euphoria brought on by this decision, I read in
the university newspaper that the visiting professor in theoreti-
cal physics for the summer quarter would be a brilliant young
man, twenty-eight years old, who had discovered the Franck-
Condon principle while a graduate student at Berkeley, had
spent two years at the great centers of theoretical physics in
Europe as a National Research Council fellow, and had held
prominent posts at the Bell Telephone Laboratories, Princeton
University, and the University of Minnesota. Just a year earlier,
he and Ronald Gurney had given an interpretation of spon-
taneous alpha disintegration of nuclei in terms of quantum
mechanical tunneling. To top it all, the campus paper related
that he had earned his way through Berkeley as one of the more
worldly reporters for the Oakland Tribune. In this pursuit he
had, among other things, stirred up a lively public discussion
of whether a birdcage would weigh more or less when the bird
was flying around inside instead of resting on its perch.
"The visitor, Edward Condon, was slated to give a course in
modern physics which would be open to duly qualified under-
graduates. I succeeded in pursuading an indulgent father to
provide the means to attend the summer session and, early i
July, found myself perched on a chair in the front row of the
lecture room waiting for the show to start. It was not a dis-
appointment.

`'Precocious and crew-cut, Ed Condon exhibited even then
all of the characteristics that have carried him through a life-
time near the center of the stage. He was creative, energetic,
perceptive, humorous, restless, eloquent, worldly and friendly.
Moreover, he knew, on a first-name basis, most of the top-billec3
physicists on the planet and loved to spin endless anecdotes
about them. This was very rich fare for an unclergraduate.
Condon's lectures . . . were there as now a wonderful combina-
tion of logic, anecdotes and humor.... In those days, long
before physicists were taken very seriously by the public at large
and when they still were all but unknown to congressmen and
security officers, Condon was flamboyantly cheerful practically
all of the time, his occasional bursts of wrath being directed at
the petty annoyances of everyday life which plague us all. His
bouts with various prominent individuals—particularly with
General Leslie Groves—lay far in the future....
"Condon was so deeply interested in other people that he
quickly came to know personally everyone in the class who
managed to act reasonably alive. The small band of embryonic
physicists who dominated the front row in the lecture hall
became his close friends.... With Condon's ardent help, con-
tinued family indulgence, ant! some permissiveness on the part
of the Princeton admissions committee, I followed him back
to Princeton a year and a half later as a graduate student....
His lectures that spring were centered on Frenkel's book about
the classical electromagnetic theory of light, which he embel-
lished in countless ways. I still cherish a carbon copy of his
notes...." ~
With the completion of The Theory of Atomic Spectra,
Condon's interest returnee! to atomic nuclei. He collaborated
with Gregory Breit on a paper on the photodisintegration of
#Wesley E. Brittin and Halis Odabasi, eds., Topics in Modern Physics; a Trib-
ute to Edward U. Condon (Boulder: Colo. Associated Univ. Press, 1971), Foreword

the deuteron. But, as he has written, "Much more important
was the work done jointly with Breit and R. D. Present on the
theoretical interpretation of the experimental results obtained
by Tuve, Hafstad, and Heydenberg at the Carnegie Institution
of Washington on the scattering of protons by protons at ener-
gies up to about one million volts. These results showed quite
clearly the charge independence of the strong nuclear force be-
tween nucleons on which all modern nuclear theory is based."
Between 1928 and 1938 Condon published two books-
Quantum Mechanics and The Theory of Atomic Spectra, both
with co-authors; nine papers on general quantum mechanics;
six papers on atomic spectra, all but one with co-authors; eight
papers on the quantum mechanics of molecules, all but two
with co-authors; two papers on solid-state theory, one with a
coauthor; and two papers on the biological effects of radiation.
In addition, there were three articles in the American Physics
Teacher on simple ways to understand physical concepts, two
on semiphilosophical topics, and one, published in the Proceed-
ings of the U.S. Naval Institute, that can be considered either
as an early example of operations research or as an example of
Ed's sense of humor. He had come across, in his -omnivorous
reading, a set of heuristic rules for the amount of food a ship-
board cook should prepare, as a function of the number of men
to be served. Assuming that the rule represents a balance be-
tween satisfying the men's shipboard appetites and reducing the
amount of food left over, he determined the parameters of the
normal distribution of the men's appetites that the rule inferred
and then embellished it with comments on the implications of
the distribution and on the validity of the conclusion that there
was a nonzero fraction of the men with negative appetites. The
conclusions seemed to puzzle some commentators in later issues
of the Proceedings. This is by way of illustrating that, in spite

University in St. Louis, and later to come to Boulder as a
professor and fellow of the Joint Institute for Laboratory Astro-
physics [joint with the Bureau of Standards, thus formally re-
establishing Ed's relationship with the Bureau that had never
really been broken]. As the cold war slowly cried down the
Department of Defense finally granted me the security clearance
which had been improperly suspended in 1954 but this, I am
proud to say, I have never used."
The appointment to Washington University was the result
of the efforts of Chancellor Arthur Compton, who not only
wanted to add an outstanding physicist to the staff, but also
realized that the nation as well as Condon would be the loser
if the irrational chain of events were allowed to continue. At
the University of Colorado he could finally settle down again to
research in atomic theory with Halis Odabasi (now at the Uni-
versity at Istanbul) with the intent of rewriting The Theory of
Atomic Spectra, and in further work on the properties of glass.
He continued to write and lecture on the need for peaceful,
worldwide cooperation; he took on the job of editor of the
Reviews of Modern Physics; he actively participated in the
research of the Joint Institute of Laboratory Astrophysics; and
he found time to be president of the American Association of
Physics Teachers in 1964.
And, in an incautious moment, he agreed to head a project,
supported by the Office of Scientific Research of the Air Force,
to investigate the many reports of uniclentified flying objects
(UFOs), with which the Air Force had been plagued for nearly
twenty years. This occupied much of his time during 1967 and
1968. The report of this project was published in 1969. Condon
gave a light-hearted accountT of some of his experiences at a
talk before the American Philosophical Society. The report has

been the subject of vituperative comment from persons anxious
to continue to believe that flying saucers are visitors from outer
space and who wish to see the government spend vast sums on
further studies. Despite the views of many of his colleagues that
the investigation was a waste of Condon's time, Seitz has said,
"The introductory chapter of the report on UFO's, in which
Condon describes with characteristic clarity his own view as a
scientist on what constitutes worthwhile research, is a classic. It
deserves to be a landmark in the journey science has taken since
the days of Stevin, Galileo and Kepler."
Edward Uhler Condon died on March 26, 1974. Two com-
ments may serve to close this survey of his life. One is by one
of his colleagues at the National Bureau of Standards, Churchill
Eisenhart: "Condon was a brilliant scientist, with highly original
ideas, a wide range of interests, a restless probing mind with
voluminous information indexed for instant retrieval. He could
meet with scientists of diverse specialities and stimulate each
with fresh enthusiasm and new insights. He could elucidate
scientific intricacies to non-scientists with clarity in layman's
language. Whatever he knew he saw with crystal clarity; he
could summarize it in a nutshell on a moment's notice or discuss
it in detail with. experts, with equal ease.
"He had an ever ready and exuberant sense of humor, a gift
of repartee and could be wittily caustic when provoked. He was
a cordial, genial, straightforward individual; fond of people,
mathematics, science, chamber music and conversation; allergic
to formality, fuzzymindedness, pomposity and all forms of physi-
cal exercise. He was an active Quaker, a firm believer in human
dignity, an outspoken liberal and anti-isolationist, who fervently
hoped that international understanding and world peace could
be furthered] by continuance of World War II alliances. He

gave freely of his counsel and his time; generously of his fi-
nances and his home." ~
The other comes from Lewis M. Branscomb, a colleague at
Boulder, now with IBM: "Watergate came as no surprise to
Edward Condon, nor did its aftermath. I imagine he would like
to have lived to see the outcome of the impeachment inquiry.
But Condon understood and paid his share of the price of
liberty. Somehow his idealism, his sense of humor and his
inexhaustible energy made his relentless quest for a better world
look like optimism. He was elected president of the AAAS
during the height of his troubles with HUAC. He was presi-
dent of the Society for Social Responsibility in Science (1968-
1969) and co-chairman of the National Committee for a Sane
Nuclear Policy (1970~. He was appropriately honored on his
retirement from JILA and the University of Colorado in the
summer of 197G by the volumeT edited by Brittin and Odabasi
mentioned earlier. Brittin relates a comment about Condon by
E. Bright Wilson: 'Sometimes I think he looks for trouble,'
Wilson said. Condon's comment: 'It's not hard to find.' "I
Unfortunately it is not easy to find a brilliant scientist who is
willing to speak out on questions of public policy, often with
humor but always with determination, even in the face of official
persecution.
