Cécile DeWitt-Morette
Encyclopedia
Cécile Andrée Paule DeWitt-Morette (born December 21, 1922) is a French mathematician and physicist. She founded a summer school at Les Houches
in the French Alps
. For this and her publications, she was awarded the American Society of the French Legion of Honor 2007 Medal for Distinguished Achievement. Attendees at the summer school included over twenty students who would go on to be Nobel Prize winners, including Pierre-Gilles de Gennes
, Georges Charpak
, and Claude Cohen-Tannoudji
, who identify the school for assisting in their success.
; she originally decided to become a surgeon. She moved to mathematics after taking a sample course to develop her education. She had to deal with a tragedy when her mother, her sister, and her grandmother were killed in the Allied bombing of Caen
to support the D-Day
landings. At the time Morette was studying in Paris. She completed her Ph.D. (Sur la Production des mésons dans les chocs entre nucléons) in 1947.
In 1948 she was invited by Robert Oppenheimer
to the Institute for Advanced Study
in Princeton, New Jersey
. Oppenheimer had just taken up the position left vacant by Albert Einstein
. There she met her future husband, although she felt guilty that she was transferring her allegiance from France to America.
She rationalised this by deciding to start a school in France in 1951. The school started with a course in quantum mechanics
and was intended to assist France following the Second World War. She founded the summer school at Les Houches
in the French Alps
. She tells stories of how she obtained the funding by tricking her way into a minister's office and then persuaded her male colleagues to support the idea by pretending that the idea was theirs. Morette was to lead this school for the next 22 years. The school was able to list twenty former students or lecturers at the school who went to become Nobel laureates. One winner of the Fields Medal
credited the summer school as responsible for his career in mathematics. Nobel laureates Pierre-Gilles de Gennes
, Georges Charpak
, and Claude Cohen-Tannoudji
identified the school as helping with their success. In 1958, NATO funded a series of advanced study centres that were based on Morette's summer school.
Morette found that she did suffer some discrimination in America. She married the American physicist Bryce DeWitt
and they had four children. Morette had originally adopted her husband's name, but found that her work was attributed to him. Later they were both visiting Professors at a University that downgraded Morette, claiming that they did this under a clause to prevent two family members having power. This was despite the significant contribution by Morette.
In 1953 a trustee of the unusual Gravity Research Foundation
, Agnew Bahnson, contacted Bryce DeWitt
with a proposal to fund a gravity research institute. The proposed name was agreed as the "Institute for Field Physics" and it was established in 1956 at the University of North Carolina at Chapel Hill
under the direction of Bryce and Morette.
In 1972 Morette and her husband led an expedition to Mauritania
to confirm that light was deflected in line with the theory of general relativity
. These measurements were made during the solar eclipse
there. Comparison of the pictures with those made six months later confirmed that, in line with theory, light was indeed bent when passing by massive objects. Morette and her husband joined the faculty of the University of Texas in 1972. She began to work increasingly in physics rather than in mathematics, and she became a Professor in 1985.
Bryce DeWitt died in 2004 from cancer. In 2007 Professor Cécile DeWitt-Morette was awarded the American Society of the French Legion of Honor 2007 Medal for Distinguished Achievement in New York. She was then the Jane and Roland Blumberg Centennial Professor Emerita of Physics at the University of Texas at Austin
