Mary K. Gaillard

Her important contributions include prediction of the mass of the charm quark prior to its discovery (with B. W. Lee); prediction of 3-jet events (with J. Ellis and G.G. Ross); and prediction of b-quark mass (with M.S. Chanowitz and J. Ellis). Gaillard's autobiography is A Singularly Unfeminine Profession, published in 2015 by World Scientific.

Gaillard served on several committees of the American Physical Society, advisory panels for the Department of Energy and the United States National Research Council, and on advisory and visiting committees at universities and national laboratories. She was a member of the National Science Board from 1996 to 2002.

Gaillard joined the physics department at the Berkeley in 1981, becoming the first woman Professor of Physics. She was concurrently a Faculty Senior Staff member at Lawrence Berkeley National Laboratory (LBNL), where she headed the Theory Group from 1985 to 1987.

Nonetheless, her scientific achievements at CERN led to her advancement at CNRS. In 1979 Gaillard established a particle theory group at the Laboratoire d'Annecy-le-Vieux de physique des particules (LAPP), Annecy-le-Vieux, France. She directed the group from 1979 to 1981. She served as Director of Research at Annecy-le-Vieux for the CNRS from 1980-1981. In 1981, the Gaillards divorced, and she returned to the United States.

At the end of her first year at Columbia she married Jean-Marc Gaillard, a visiting physics postdoctoral student. She moved with him, first to the University of Paris at Orsay, France and a year later to the European Organization for Nuclear Research (CERN) in Geneva, Switzerland. Despite experiencing sexism and having three children, she continued to study theoretical physics. In 1964 she obtained her Doctorat du Troisième Cycle from the University of Paris at Orsay, France. In 1968, she completed her Doctorat d'Etat in Theoretical Physics there.

During her time at CERN (1964-1981) Gaillard was considered a visiting scientist, first as a student from Orsay, and later as a research scientist employed by the French National Centre for Scientific Research (CNRS). At one point, she carried out and submitted a survey of women scientists at CERN, documenting clear patterns of blatant sexism against women scientists in hiring and salaries.

She attended Hollins College in Virginia as an undergraduate. Her physics professor, Dorothy Montgomery, helped her to find work in the Louis Leprince-Ringuet laboratory in France during a year abroad, and at Brookhaven National Labs in the summer. She received her bachelor's degree from Hollins in 1960. She received her master's degree from Columbia University in 1961.

Mary Katharine Gaillard (born April 1, 1939) is an American theoretical physicist. Her focus is on particle physics. She is a professor of the Graduate School at the University of California, Berkeley, a member of the Berkeley Center for Theoretical Physics, and visiting scientist at the Lawrence Berkeley National Laboratory. She was Berkeley's first tenured female physicist.

Mary Katharine Ralph was born April 1, 1939 in New Brunswick, New Jersey, and grew up in Painesville, Ohio, where her father taught history at Lake Erie College.
