The ILAS Taussky-Todd Prize was established by the Board of Directors in 2021. The prize is named for Olga Taussky and John Todd, who had a decisive impact on the development of theoretical and numerical linear algebra for over half a century. This prize honors them for their many and varied mathematical achievements and for their efforts in promoting linear algebra and matrix theory. The Taussky-Todd Prize replaces the Taussky-Todd lecture, which was instituted at the 3rd ILAS meeting held at the University of West Florida in Pensacola, Florida, March 17–20, 1993.
