He graduated from Queen's University in Belfast (Northern Ireland) in 1931 and enrolled at the University of Cambridge, working under J.E. Littlewood and G.H. Hardy. Littlewood did not have a doctorate and disapproved of doctoral degrees, so Todd never received a higher degree, eventually becoming one of the very few professors at the California Institute of Technology (Caltech) without one. After the end of World War II in Europe, during which Todd served in the British Admiralty, he saved the Mathematical Research Institute at Oberwolfach from being destroyed, calling it "probably the best thing I ever did for mathematics."

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. Our sense of collegiality and common purpose are a tribute to them." Todd was an AMS member since 1948.
