2006 FIP Pioneer Award presented to Dr. Charles Townes, Nobel Laureate
Charles Hard Townes was born
in Greenville, South Carolina, on July 28, 1915, the son of Henry Keith Townes,
an attorney, and Ellen (Hard) Townes. He attended the Greenville public schools
and then Furman University in Greenville, where he completed the requirements
for the Bachelor of Science degree in Physics and the Bachelor of Arts degree
in Modern Languages, graduating
summa cum laude in 1935, at the age
of 19. Physics had fascinated him since his first course in the subject during
his sophomore year in college because of its "beautifully logical structure".
He was also interested in natural history while at Furman, serving as curator
of the museum, and working during the summers as collector for Furman's biology
camp. In addition, he was busy with other activities, including the swimming
team, the college newspaper and the football band.
Townes completed work for the Master of Arts degree in Physics at Duke
University in 1936, and then entered graduate school at the California Institute
of Technology, where he received the Ph.D. degree in 1939 with a thesis on
isotope separation and nuclear spins.
A member of the technical staff of Bell Telephone Laboratories from 1933 to
1947, Dr. Townes worked extensively during World War II in designing radar
bombing systems and has a number of patents in related technology. From this
he turned his attention to applying the microwave technique of wartime radar
research to spectroscopy, which he foresaw as providing a powerful new tool
for the study of the structure of atoms and molecules and as a potential new
basis for controlling electromagnetic waves.
At Columbia University, where he was appointed to the faculty in 1948, he
continued research in microwave physics, particularly studying the interactions
between microwaves and molecules, and using microwave spectra for the study
of the structure of molecules, atoms, and nuclei. In 1951, Dr. Townes conceived
the idea of the maser, and a few months later he and his associates began working
on a device using ammonia gas as the active medium. In early 1954, the first
amplification and generation of electromagnetic waves by stimulated emission
were obtained. Dr. Townes and his students coined the word "maser" for
this device, which is an acronym for microwave amplification by stimulated
emission of radiation. In 1958, Dr. Townes and his brother-in-law, Dr. A.L.
Schawlow, for some time a professor at Stanford University but now deceased,
showed theoretically that masers could be made to operate in the optical and
infrared region and proposed how this could be accomplished in particular systems.
This work resulted in their joint paper on optical and infrared masers, or
lasers (light amplification by stimulated emission of radiation). Other research
has been in the fields of nonlinear optics, radio astronomy, and infrared astronomy.
He and his assistants detected the first complex molecules in interstellar
space and first measured the mass of the black hole in the center of our galaxy.
Having joined the faculty at Columbia University as Associate Professor of
Physics in 1948, Townes was appointed Professor in 1950. He served as Executive
Director of the Columbia Radiation Laboratory from 1950 to 1952 and was Chairman
of the Physics Department from 1952 to 1955.
From 1959 to 1961, he was on leave of absence from Columbia University to serve
as Vice President and Director of Research of the Institute for Defense Analyses
in Washington, D.C., a nonprofit organization which advised the U.S. government
and was operated by eleven universities.
In 1961, Dr. Townes was appointed Provost and Professor of Physics at the Massachusetts
Institute of Technology. As Provost he shared with the President responsibility
for general supervision of the educational and research programs of the Institute.
In 1966, he became Institute Professor at M.I.T., and later in the same year
resigned from the position of Provost in order to return to more intensive
research, particularly in the fields of quantum electronics and astronomy.
He was appointed University Professor at the University of California in 1967.
In this position Dr. Townes is participating in teaching, research, and other
activities on several campuses of the University, although he is located at
the Berkeley campus.
During 1955 and 1956, Townes was a Guggenheim Fellow and a Fulbright Lecturer,
first at the University of Paris and then at the University of Tokyo. He was
National Lecturer for Sigma Xi and also taught during summer sessions at the
University of Michigan and at the Enrico Fermi International School of Physics
in Italy, serving as Director for a session in 1963 on coherent light. In
the fall of 1963, he was Scott Lecture at the University of Toronto. More
recently (2002-2003) he has been the Karl Schwarzschild Lecturer in Germany
and the Birla Lecturer and Schroedinger Lecturer in India.
In addition to the Nobel Prize, Townes has received the Templeton Prize, for
contributions to the understanding of religion, and a number of other prizes
as well as 27 honorary degrees from various universities.
Dr. Townes has served on a number of scientific committees advising governmental
agencies and has been active in professional societies. This includes being
a member, and vice chairman, of the Science Advisory Committee to the President
of the U.S., Chairman of the Advisory Committee for the first human landing
on the moon, and chairman of the Defense Department’s Committee on the
MX missile. He also served on the boards of General Motors and of the Perkins
Elmer Corporations.
Dr. Townes and his wife (the former Frances H. Brown; they married in 1941)
live at 1988 San Antonio Avenue, Berkeley, California. They have four daughters,
Linda Rosenwein, Ellen Anderson, Carla Kessler, and Holly Townes.
