Mary Tsingou

Mary Tsingou (married name: Mary Tsingou-Menzel; born October 14, 1928)^[1] is an American physicist and mathematician of Greek ancestry.

Born in Milwaukee, Wisconsin, her parents moved to the US from Bulgaria and were Greek. She spent several years in Bulgaria before returning to the US to attend high school and college. Menzel attended the University of Wisconsin where she majored in mathematics and education.

She is known in the computational physics community for having helped in the coding of the Fermi–Pasta–Ulam problem at the Los Alamos National Laboratory while working as a programmer in the MANIAC group.^[2][3] The result was an important stepping stone for chaos theory.

Recent calls have been made to rename the phenomenon the Fermi–Pasta–Ulam-Tsingou problem, to honour her contribution.^[4][5]
