Emilie Virginia Haynsworth (June 1, 1916 – May 4, 1985)[1] was an American mathematician at Auburn University who worked in linear algebra and matrix theory.
She gave the name to Schur complements and is the namesake of the Haynsworth inertia additivity formula.
She earned a master's degree in 1939 from Columbia University in New York City, and became a high school mathematics teacher.
[1] Her dissertation, Bounds for Determinants with Dominant Main Diagonal, was supervised by Alfred Brauer.
She moved to the National Bureau of Standards in 1955, and returned to academia in 1960 as a faculty member in mathematics at Auburn University.
