Bruria Kaufman (August 21, 1918 – January 7, 2010) was an American theoretical physicist. She is known for contributions to Albert Einstein's general theory of relativity, to statistical physics, where she used applied spinor analysis to rederive the result of Lars Onsager on the partition function of the two-dimensional Ising model, and to the study of the Mössbauer effect, on which she collaborated with John von Neumann and Harry Lipkin.
Bruria Kaufman was born in New York City to a Jewish family of Ukrainian origin. In 1926 the family immigrated to the British Mandate for Palestine, living first in Tel Aviv, and then in Jerusalem. Her main interests during her youth were music and mathematics.
Kaufman returned to the US in 1982. They lived in Pennsylvania, where her husband taught. He died in 1992. Kaufman moved to Arizona and married the Nobel laureate Willis Eugene Lamb in 1996, although the marriage ended in divorce. She died in January 2010 at Carmel Hospital in Haifa, following a stay at a nursing home in Kiryat Tiv'on, not far from Haifa. In keeping with her wishes, her body was cremated.
Kaufman was a research associate at the Institute for Advanced Study in Princeton from 1948 to 1955, where she worked with John von Neumann (1947/48) and with Albert Einstein (1950–1955). She spent the following years at the University of Pennsylvania working on a mathematical linguistics project.
