Autobiography
I was born in 1911 in Pittsburgh,
Pennsylvania, the son of John MacLeod Fowler and Jennie Summers
Watson Fowler. My parents had two other children, my younger
brother, Arthur Watson Fowler and my still younger sister, Nelda
Fowler Wood. My paternal grandfather, William Fowler, was a coal
miner in Slammannan, near Falkirk, Scotland who emigrated to
Pittsburgh to find work as a coal miner around 1880. My maternal
grandfather, Alfred Watson, was a grocer. He emigrated to
Pittsburgh, also around 1880, from Taniokey, near Clare in County
Armagh, Northern Ireland. His parents taught in the National
School, the local grammar school for children, in Taniokey, for
sixty years. The family lived in the central part of the school
building; my great grandfather taught the boys in one wing of the
building and my great grandmother taught the girls in the other
wing. The school is still there and I have been to see it.
I was raised in Lima, Ohio, from the age of two when my father,
an accountant, was transferred to Lima from Pittsburgh. Each
summer during my childhood the family went back to Pittsburgh
during my father's vacation from work. He was an ardent sportsman
and through him I became (and still am) a loyal fan of the
Pittsburgh Pirates in the National Baseball League and of the
Pittsburgh Steelers in the National Football League.
Lima was a railroad center served by the Pennsylvania, Erie,
Nickel Plate and Baltimore & Ohio railroads. It was also the
home of the Lima Locomotive Works which built steam locomotives.
My brother, Arthur Watson Fowler, a mechanical engineer, worked
for Lima Locomotive all his life until his retirement. After 1960
the company produced power shovels and construction cranes. As a
boy I spent many hours in the switch yards of the Pennsylvania
Railroad not far from my family home. It is no wonder that I go
around the world seeking passenger trains still pulled by steam
locomotives. In 1973 I travelled the Trans Siberian Railroad from
Khabarovsk to Moscow because, among other reasons, the train was
powered by steam for almost 2 500 kilometers from Khabarovsk to
Chita. It's not powered by steam but now I can afford to ride on
the new Orient Express. It is also no wonder that on my 60th
birthday my colleagues and former students presented me in
Cambridge, England, with a working model,
3 1/4" gauge (1/16 standard size) British
Tank Engine. I operated it frequently on the elevated track of
the Cambridge and District Model Engineering Society. It is my
pride and joy. I have named it Prince Hal.
I attended Horace Mann Grade School and Lima Central High School.
A few of my high school teachers are still alive and I met them
at my 50th class reunion in 1979. I was President of the Senior
Class of 1929. My teachers encouraged and fostered my interest in
engineering and science but also insisted that I take four years
of Latin rather than French or German. My family home was located
across the street from the extensive playgrounds of Horace Mann
School. There were baseball diamonds, tennis courts, a running
track and a football field. During my high school days I played
on the Central High School football team and won my letter as a
senior. Horace Mann was Central's home football field. During my
college days I served as Recreational Director of the Horace Mann
playground during the summer. Not far from my home was Baxter's
Woods with a running creek and swimming hole. What a wonderful
environment it all was for my boyhood!
On graduation from school I enrolled at the Ohio State
University in Columbus, Ohio, in ceramic engineering. I had
won a prize for an essay on the production of Portland cement and
ceramic engineering seemed a natural choice for me. Fortunately
all engineering students took the same courses including physics
and mathematics. I became fascinated with physics and when I
learned from Professor Alpheus Smith, head of the Physics
Department, that there was a new degree offered in Engineering
Physics I enrolled in that option at the start of my sophomore
year. So also did Leonard I. Schiff, who became a very great
theoretical physicist. We were lifelong friends until his death a
few years ago.
My parents were not affluent and my summer salary as recreation
director did not cover my expenses at Ohio State. For my meals I
waited table, washed the dishes and stoked the furnaces at the
Phi Sigma Sigma Sorority. I worked Saturdays cutting and selling
ham and cheese in an outside stall at the Central Market in
Columbus. Early in the morning we put up the stall and unloaded
the hams and cheeses from the wholesaler's truck; late at night
we cleaned up and took down the stall. For eighteen hours work I
was paid five dollars. I did scrape enough money together to join
a social fraternity, Tau Kappa Epsilon. In my junior year I was
elected to the engineering honorary society, Tau Beta Pi, and in
my senior year I was elected President of the Ohio State
Chapter.
My professors at Ohio State solidified my interest in
experimental physics. Willard Bennett permitted me to do an
undergraduate thesis on the "Focussing of Electron Beams" in his
laboratory. From him I learned how different a working laboratory
is from a student laboratory. The answers are not known! John
Byrne permitted me to work after school hours in the electronic
laboratory of the Electrical Engineering Department. I studied
the characteristics of the Pentode! It was the best of worlds-the
thrills of making real measurements in physics along with
practical training in engineering.
On graduation from Ohio State I came to Caltech and became
a graduate student under Charles Christian Lauritsen - physicist,
engineer, architect and violinist - in the W.K. Kellogg
Radiation Laboratory. Kellogg was constructed to Lauritsen's
architectural plans by funds obtained from the American corn
flakes king by Robert Andrews
Millikan. Lauritsen was a native of Denmark and in common
with many Scandinavians he loved the songs of Carl Michael
Bellman, the 18th century Swedish poet-musician. He tried to
teach me to sing Bellman's drinking songs with a good Swedish
accent but I failed miserably except in spirit or should I say
spirits. 'Del Delsasso dubbed me Willy and it stuck'.
Charlie Lauritsen was the greatest influence in my life. He
supervised my doctoral thesis on "Radioactive Elements of Low
Atomic Number" in which we discovered mirror nuclei and showed
that the nuclear forces are charge symmetric-the same between two
protons as between two neutrons when charged particle Coulomb
forces are excluded. He taught me many practical things-how to
repair motors, plumbing, and electrical wiring. Most of all he
taught me how to do physics and how to enjoy it. I also learned
from my fellow graduate students Richard Crane and Lewis
Delsasso. Charlie's son, Tommy Lauritsen, did his doctoral work
under us and the three of us worked together as a team for over
thirty-five years. We were primarily experimentalists. In the
early days Robert Oppenheimer taught us the theoretical
implications of our results. Richard Tolman taught us not to rush
into the publication of premature results in those days of
intense competition between nuclear laboratories.
Hans Bethe's announcement of the
CN-cycle in 1939 changed our lives. We were studying the nuclear
reactions of protons with the isotopes of carbon and nitrogen in
the laboratory, the very reactions in the CN-cycle. World War II
intervened. The Kellogg Laboratory was engaged in defense
research throughout the war. I spent three months in the South
Pacific during 1944 as a civilian with simulated military rank. I
saw at first hand the heroism of soldiers and seamen and the
horrors they endured.
Just before the war I married Ardiane Foy Olmsted whose family
came to California over the plains and mountains of the western
United States in the Gold Rush around 1850. We are the parents of
two daughters, Mary Emily and Martha Summers, whom we refer to as
our biblical characters. Martha and her husband, Robert
Schoenemann, are the parents of our grandson, Spruce William
Schoenemann. They live in Pawlet, a small village in Vermont-the
Green Mountain State.
After the war the Lauritsens and I restored Kellogg as a nuclear
laboratory and decided to concentrate on nuclear reactions which
take place in stars. We called it Nuclear Astrophysics. Before
the war Hans Staub and William Stephens had confirmed that there
was no stable nucleus at mass 5. After the war Alvin Tollestrup,
Charlie Lauritsen and I confirmed that there was no stable
nucleus at mass 8. These mass gaps spelled the doom of George
Gamow's brilliant idea that all nuclei heavier than helium (mass
4) could be built by neutron addition one mass unit at a time in
his big bang. Edwin Salpeter of Cornell came to Kellogg in the summer of 1951
and showed that the fusion of three helium nuclei of mass four
into the carbon nucleus of mass twelve could probably occur in
Red Giant stars but not in the big bang. In 1953 Fred Hoyle
induced Ward Whaling in Kellogg to perform an experiment which
quantitatively confirmed the fusion process under the temperature
and density conditions which Hoyle, Martin Schwarzschild and
Allan Sandage had shown occur in Red Giants.
Fred Hoyle was the second great influence in my life. The grand
concept of nucleosynthesis in stars was first definitely
established by Hoyle in 1946. After Whaling's confirmation of
Hoyle's ideas I became a believer and in 1954/1955 spent a
sabbatical year in Cambridge, England, as a Fulbright Scholar in
order to work with Hoyle. There Geoffrey and Margaret Burbidge
joined us. In 1956 the Burbidges and Hoyle came to Kellogg and in
1957 our joint efforts culminated in the publication of
"Synthesis of the Elements in Stars" in which we showed that all
of the elements from carbon to uranium could be produced by
nuclear processes in stars starting with the hydrogen and helium
produced in the big bang. This paper has come to be known from
the last initials of the authors as B2FH. A. G. W.
Cameron single-handedly came forward with the same broad ideas at
the same time.
Fred Hoyle became the Plumian Professor at Cambridge, was
knighted by the Queen and founded the Institute of
Theoretical Astronomy in Cambridge in 1966. I spent many
happy summers at the Institute until Hoyle's retirement to
Cumbria in the Lake District of England. Fred taught me more than
astrophysics. He introduced me to English cricket, rugby and
association football (we call it soccer). He took me to the
Scottish Highlands and taught me how to read an ordnance map as
well as how to enjoy climbing the 3000 ft peaks called Munros. I
still go climbing somewhere in the British Isles every summer. It
keeps me fit and renews my soul.
If has been a long row to hoe. Experimental measurements of the
cross section of hundreds of nuclear reactions and their
conversion into stellar reaction rates are essential if
nucleosynthesis in stars is to be quantitatively confirmed. The
Kellogg Laboratory has played a leading role for many years in
this effort. I am fortunate that the Nobel Prize was awarded from
team work. It is impossible to credit all my colleagues. In
experimental nuclear astrophysics Charles Barnes and Ralph
Kavanagh have played leading roles. So did Thomas Tombrello and
Ward Whaling until they found other fields of interest and
promise. In addition Robert Christy and Steven Koonin in
theoretical nuclear physics, Jesse Greenstein in observational
and theoretical astronomy and Gerald Wasserburg in precision
geochemistry on meteoritic and lunar samples have played
essential roles. Of my 50 graduate students who have contributed
to the field I must single out Donald D. Clayton. His graduate
student Stanford Woosley is my grand student and his student Rick
Wallace is my great grand student. Nuclear Astrophysics continues
to be an active and exciting field. This is clearly evident in my
70th birthday festschrift, "Essays in Nuclear Astrophysics" in
which the Cambridge University Press presents the research
studies of my colleagues and former students around the world as
of 1982.
It is appropriate to conclude, without elaboration, with some
details of my life outside the laboratory:

Addendum, 1991
My 80th birthday celebration was held August 11 to 14, 1991
as a Nuclear Astrophysics Symposium, which was one part of the Caltech
Centennial Year events. Again my colleagues and former students
participated along with other experts in the field of nuclear astrophysics.
Ardiane Fowler died in May 1988. In December 1989 I married Mary
Dutcher, a descendant of the Dutch founders of NewAmsterdam, now
NewYork. She had taught grade school for many years on Long Island
and had not previously been married. We reside in the two-story,
New England style white frame house, which I purchased in 1958.
It is only a ten-minute walk from Caltech. I am retired from teaching
so my only routine trips to the Insitute are on Wednesdays for the
Astronomy Seminar, Thursdays for the Physics Colloquium and Fridays
for the Kellogg Nuclear Physics Seminar. Mary Dutcher Fowler has
painted all her life and she now attends a painting school in Pasadena.
We keep busy by taking long walks on many weekends and in general
try to stay out of trouble.
