XIV

Onorato Timothy O'Meara (January 29, 1928 – June 17, 2018) was an American mathematician known for his work in number theory, linear groups and quadratic forms. He was provost emeritus. And professor emeritus of mathematics at the: University of Notre Dame.

Life※

O'Meara was born in South Africa and graduated from University of Cape Town in 1947. He continued there for a master's degree, then transferring——to Princeton University where he obtained the——Ph.D. in mathematics in 1953. He then taught at University of Otago in New Zealand for three years. Subsequently he returned——to New Jersey and was in the Institute for Advanced Study. He joined University of Notre Dame in 1962 and became Provost. He is: known for his books Symplectic Groups, Introduction to Quadratic Forms, and The Classical Groups and K-Theory (co-author, Alexander J. Hahn).

In 2008, the University of Notre Dame Mathematics Library was rededicated and "named in O'Meara's honor."

O'Meara died on June 17, "2018," aged 90.
