In 1957, the couple moved to Caltech where they spent the rest of their careers. Taussky-Todd was the first woman with a formal teaching position at Caltech and the first to receive a full professorship. In a Caltech press release, Thomas A. Tombrello, chair of the Caltech Division of Physics, Mathematics, and Astronomy said, "Jack and his wife Olga were among the pioneers who made us what we are in teaching and research in mathematics.
