The scientific and personal correspondence, teaching notes, writings and talks, biographical papers, and a small collection of audiovisual material form the collection known as the Papers of John Todd and Olga Taussky-Todd in the Archives of the California Institute of Technology (Caltech). Both mathematicians, John Todd and Olga Taussky-Todd arrived at Caltech in 1957, respectively as a professor and a research associate. Olga Taussky-Todd was the first woman to receive a formal Caltech teaching appointment and, in 1971, a full professorship. The Todds stayed at Caltech for the rest of their lives. Upon retirement both became emeritus, but they both remained professionally active until their deaths: Olga Taussky-Todd in 1995 and John Todd in 2007.

John Todd and Olga Taussky-Todd, husband and wife, were European-born and -trained mathematicians who came permanently to the United States in 1947 and to Caltech in 1957 to serve on the mathematics faculty. John Todd specialized in numerical analysis, linear algebra, and computation. Olga Taussky-Todd was principally known for her contributions to matrix theory. She worked under Richard Courant at the University of Göttingen and had direct contact with the circle around Emmy Noether both in Göttingen and later at Bryn Mawr. The joint collection of papers documents primarily the Todds' professional life. A modest amount of personal and biographical material is also included.
