Mary Tsingou

In 2008, an article published in Physics Today called to rename the FPU problem to the FPUT problem to give her proper credit for her contribution. Subsequent publications referencing the FPUT problem reflect this change. In 2020, National Security Science magazine, published by Los Alamos National Laboratory, featured an article on Tsingou that included her commentary and historical reflections on the FPUT problem. The article was titled "We thank Miss Mary Tsingou" in reference to the acknowledgement that appeared on the title page of the original FPUT technical report from 1955.

Tsingou-Menzel continued her computational career at Los Alamos. She was an early expert on Fortran. In the 1980s, she worked on calculations in the Star Wars program. She retired in 1991.

Mary Tsingou was born in Milwaukee, Wisconsin, her Greek parents having moved to the US from Bulgaria. In the aftermath of the Great Depression, the family left the US to spend several years in Bulgaria. In 1940, they returned to the US, where Tsingou attended high school and college. She graduated in mathematics and education in 1951 from the University of Wisconsin. She then studied at the University of Michigan, receiving a master's degree in mathematics in 1955. In 1958, she married Joseph Menzel.

Mary Tsingou (married name: Mary Tsingou-Menzel; born October 14, 1928) is an American physicist and mathematician of Greek descent. She was one of the first programmers on the MANIAC computer at Los Alamos National Laboratory and is best known for having coded the celebrated computer experiment with Enrico Fermi, John Pasta, and Stanislaw Ulam which became an inspiration for the fields of chaos theory and scientific computing and was a turning point in soliton theory.
