Mary K. Gaillard

Theoretical physicist Mary K. Gaillard received her undergraduate degree from Hollins College in 1960 and her PhD in physics from Université Paris-Sud, Orsay in 1968. She was a visitor in the Fermilab Theory Department from 1973 to 1974. While at Fermilab, she worked with theoretical physicist Benjamin W. Lee, and together they predicted the mass of the charm quark. She was also at CERN from 1968 until 1981, when she joined Lawrence Berkeley National Laboratory and the University of California, Berkeley, becoming the first woman to hold a tenured position on the university’s physics faculty. Gaillard retired in 2009, but she remained a professor at the University of California and a visiting scientist at Lawrence Berkeley National Laboratory. She published her autobiography A Singularly Unfeminine Profession: One Woman's Journey in Physics in 2015. She passed away in 2025.
