Autobiography
My beginning as a legally recognized
individual occurred on June 13, 1928 in Bluefield, West Virginia,
in the Bluefield Sanitarium, a hospital that no longer exists. Of
course I can't consciously remember anything from the first two
or three years of my life after birth. (And, also, one suspects,
psychologically, that the earliest memories have become "memories
of memories" and are comparable to traditional folk tales passed
on by tellers and listeners from generation to generation.) But
facts are available when direct memory fails for many
circumstances.
My father, for whom I was named, was an electrical engineer and
had come to Bluefield to work for the electrical utility company
there which was and is the Appalachian Electric Power Company. He
was a veteran of WW1 and had served in France as a lieutenant in
the supply services and consequently had not been in actual front
lines combat in the war. He was originally from Texas and had
obtained his B.S. degree in electrical engineering from Texas
Agricultural and Mechanical (Texas A. and M.).
My mother, originally Margaret Virginia Martin, but called
Virginia, was herself also born in Bluefield. She had studied at
West Virginia University and was a school teacher before her
marriage, teaching English and sometimes Latin. But my mother's
later life was considerably affected by a partial loss of hearing
resulting from a scarlet fever infection that came at the time
when she was a student at WVU.
Her parents had come as a couple to Bluefield from their original
homes in western North Carolina. Her father, Dr. James Everett
Martin, had prepared as a physician at the University of Maryland
in Baltimore and came to Bluefield, which was then expanding
rapidly in population, to start up his practice. But in his later
years Dr. Martin became more of a real estate investor and left
actual medical practice. I never saw my grandfather because he
had died before I was born but I have good memories of my
grandmother and of how she could play the piano at the old house
which was located rather centrally in Bluefield.
A sister, Martha, was born about two and a half years later than
me on November 16, 1930.
I went to the standard schools in Bluefield but also to a
kindergarten before starting in the elementary school level. And
my parents provided an encyclopedia, Compton's Pictured
Encyclopedia, that I learned a lot from by reading it as a child.
And also there were other books available from either our house
or the house of the grandparents that were of educational
value.
Bluefield, a small city in a comparatively remote geographical
location in the Appalachians, was not a community of scholars or
of high technology. It was a center of businessmen, lawyers, etc.
that owed its existence to the railroad and the rich nearby coal
fields of West Virginia and western Virginia. So, from the
intellectual viewpoint, it offered the sort of challenge that one
had to learn from the world's knowledge rather than from the
knowledge of the immediate community.
By the time I was a student in high school I was reading the
classic "Men of Mathematics" by E.T. Bell and I remember
succeeding in proving the classic Fermat theorem about an integer
multiplied by itself p times where p is a prime.
I also did electrical and chemistry experiments at that time. At
first, when asked in school to prepare an essay about my career,
I prepared one about a career as an electrical engineer like my
father. Later, when I actually entered Carnegie Tech. in
Pittsburgh I entered as a student with the major of chemical
engineering.
Regarding the circumstances of my studies at Carnegie (now
Carnegie Mellon
U.), I was lucky to be there on a full scholarship, called
the George Westinghouse Scholarship. But after one semester as a
chem. eng. student I reacted negatively to the regimentation of
courses such as mechanical drawing and shifted to chemistry
instead. But again, after continuing in chemistry for a while I
encountered difficulties with quantitative analysis where it was
not a matter of how well one could think and understand or learn
facts but of how well one could handle a pipette and perform a
titration in the laboratory. Also the mathematics faculty were
encouraging me to shift into mathematics as my major and
explaining to me that it was not almost impossible to make a good
career in America as a mathematician. So I shifted again and
became officially a student of mathematics. And in the end I had
learned and progressed so much in mathematics that they gave me
an M. S. in addition to my B. S. when I graduated.
I should mention that during my last year in the Bluefield
schools that my parents had arranged for me to take supplementary
math. courses at Bluefield College, which was then a 2-year
institution operated by Southern Baptists. I didn't get official
advanced standing at Carnegie because of my extra studies but I
had advanced knowledge and ability and didn't need to learn much
from the first math. courses at Carnegie.
When I graduated I remember that I had been offered fellowships
to enter as a graduate student at either Harvard or Princeton. But
the Princeton fellowship was somewhat more generous since I had
not actually won the Putnam competition and also Princeton seemed
more interested in getting me to come there. Prof. A.W. Tucker
wrote a letter to me encouraging me to come to Princeton and from
the family point of view it seemed attractive that geographically
Princeton was much nearer to Bluefield. Thus Princeton became the
choice for my graduate study location.
But while I was still at Carnegie I took one elective course in
"International Economics" and as a result of that exposure to
economic ideas and problems, arrived at the idea that led to the
paper "The Bargaining Problem" which was later published in
Econometrical. And it was this idea which in turn, when I was a
graduate student at Princeton, led to my interest in the game
theory studies there which had been stimulated by the work of von
Neumann and Morgenstern.
As a graduate student I studied mathematics fairly broadly and I
was fortunate enough, besides developing the idea which led to
"Non-Cooperative Games", also to make a nice discovery relating
to manifolds and real algebraic varieties. So I was prepared
actually for the possibility that the game theory work would not
be regarded as acceptable as a thesis in the mathematics
department and then that I could realize the objective of a Ph.D.
thesis with the other results.
But in the event the game theory ideas, which deviated somewhat
from the "line" (as if of "political party lines") of von Neumann
and Morgenstern's book, were accepted as a thesis for a
mathematics Ph.D. and it was later, while I was an instructor at
M.I.T., that I
wrote up Real Algebraic Manifolds and sent it in for
publication.
I went to M.I.T. in the summer of 1951 as a "C.L.E. Moore
Instructor". I had been an instructor at Princeton for one year
after obtaining my degree in 1950. It seemed desirable more for
personal and social reasons than academic ones to accept the
higher-paying instructorship at M.I.T.
I was on the mathematics faculty at M.I.T. from 1951 through
until I resigned in the spring of 1959. During academic 1956 -
1957 I had an Alfred P. Sloan grant and chose to spend the year
as a (temporary) member of the Institute for Advanced Study in
Princeton.
During this period of time I managed to solve a classical
unsolved problem relating to differential geometry which was also
of some interest in relation to the geometric questions arising
in general relativity. This was the problem to prove the
isometric embeddability of abstract Riemannian manifolds in flat
(or "Euclidean") spaces. But this problem, although classical,
was not much talked about as an outstanding problem. It was not
like, for example, the 4-color conjecture.
So as it happened, as soon as I heard in conversation at M.I.T.
about the question of the embeddability being open I began to
study it. The first break led to a curious result about the
embeddability being realizable in surprisingly low-dimensional
ambient spaces provided that one would accept that the embedding
would have only limited smoothness. And later, with "heavy
analysis", the problem was solved in terms of embeddings with a
more proper degree of smoothness.
While I was on my "Sloan sabbatical" at the IAS in Princeton I
studied another problem involving partial differential equations
which I had learned of as a problem that was unsolved beyond the
case of 2 dimensions. Here, although I did succeed in solving the
problem, I ran into some bad luck since, without my being
sufficiently informed on what other people were doing in the
area, it happened that I was working in parallel with Ennio de
Giorgi of Pisa, Italy. And de Giorgi was first actually to
achieve the ascent of the summit (of the figuratively described
problem) at least for the particularly interesting case of
"elliptic equations".
It seems conceivable that if either de Giorgi or Nash had failed
in the attack on this problem (of a priori estimates of Holder
continuity) then that the lone climber reaching the peak would
have been recognized with mathematics' Fields medal (which has
traditionally been restricted to persons less than 40 years
old).
Now I must arrive at the time of my change from scientific
rationality of thinking into the delusional thinking
characteristic of persons who are psychiatrically diagnosed as
"schizophrenic" or "paranoid schizophrenic". But I will not
really attempt to describe this long period of time but rather
avoid embarrassment by simply omitting to give the details of
truly personal type.
While I was on the academic sabbatical of 1956-1957 I also
entered into marriage. Alicia had graduated as a physics major
from M.I.T. where we had met and she had a job in the New York
City area in 1956-1957. She had been born in El Salvador but came
at an early age to the U.S. and she and her parents had long been
U.S. citizens, her father being an M. D. and ultimately employed
at a hospital operated by the federal government in
Maryland.
The mental disturbances originated in the early months of 1959 at
a time when Alicia happened to be pregnant. And as a consequence
I resigned my position as a faculty member at M.I.T. and,
ultimately, after spending 50 days under "observation" at the
McLean Hospital, travelled to Europe and attempted to gain status
there as a refugee.
I later spent times of the order of five to eight months in
hospitals in New Jersey, always on an involuntary basis and
always attempting a legal argument for release.
And it did happen that when I had been long enough hospitalized
that I would finally renounce my delusional hypotheses and revert
to thinking of myself as a human of more conventional
circumstances and return to mathematical research. In these
interludes of, as it were, enforced rationality, I did succeed in
doing some respectable mathematical research. Thus there came
about the research for "Le Probleme de Cauchy pour les E'quations
Differentielles d'un Fluide Generale"; the idea that Prof.
Hironaka called "the Nash blowing-up transformation"; and those
of "Arc Structure of Singularities" and "Analyticity of Solutions
of Implicit Function Problems with Analytic Data".
But after my return to the dream-like delusional hypotheses in
the later 60's I became a person of delusionally influenced
thinking but of relatively moderate behavior and thus tended to
avoid hospitalization and the direct attention of
psychiatrists.
Thus further time passed. Then gradually I began to
intellectually reject some of the delusionally influenced lines
of thinking which had been characteristic of my orientation. This
began, most recognizably, with the rejection of
politically-oriented thinking as essentially a hopeless waste of
intellectual effort.
So at the present time I seem to be thinking rationally again in
the style that is characteristic of scientists. However this is
not entirely a matter of joy as if someone returned from physical
disability to good physical health. One aspect of this is that
rationality of thought imposes a limit on a person's concept of
his relation to the cosmos. For example, a non-Zoroastrian could
think of Zarathustra as simply a madman who led millions of naive
followers to adopt a cult of ritual fire worship. But without his
"madness" Zarathustra would necessarily have been only another of
the millions or billions of human individuals who have lived and
then been forgotten.
Statistically, it would seem improbable that any mathematician or
scientist, at the age of 66, would be able through continued
research efforts, to add much to his or her previous
achievements. However I am still making the effort and it is
conceivable that with the gap period of about 25 years of
partially deluded thinking providing a sort of vacation my
situation may be atypical. Thus I have hopes of being able to
achieve something of value through my current studies or with any
new ideas that come in the future.
