Charles Royal Johnson (born January 28, 1948) is an American mathematician specializing in linear algebra. He was a Class of 1961 professor of mathematics at College of William and Mary. ^[1] The books Matrix Analysis and Topics in Matrix Analysis, co-written by him with Roger Horn, are standard texts in advanced linear algebra. ^{[2] [3] [4]}

Career

Johnson received a B.A. with distinction in Mathematics and Economics from Northwestern University in 1969. In 1972, he received a Ph.D. in Mathematics and Economics from the California Institute of Technology, where he was advised by Olga Taussky Todd; his dissertation was entitled "Matrices whose Hermitian Part is Positive Definite". ^[5] Johnson held various professorships over ten years at the University of Maryland, College Park starting in 1974. He was a professor at Clemson University from 1984 to 1987.^{[ citation needed ]} He was a professor of mathematics at the College of William and Mary from 1987 to 2024. ^[6]
