Joseph Dennis (mathematician)
Joseph James Dennis was an African-American mathematician and served as the chairman of the Clark College mathematics department from 1930 to 1974.
Dennis gained his B.A. from Clark College in 1929, and his M.A. from Northwestern University in 1935. He earned his Ph.D. at Northwestern University in 1944. This is the same year as two other African-American men earned a Ph.D in mathematics, Wade Ellis Sr. and Warren Hill Brothers. His thesis was "Some Points in the Theory of Positive Definite J-Fractions", supervised by H. S. Wall. He was one of the first African Americans to earn a PhD.
A building, and a scholarship fund for junior and senior mathematics majors at Clark University, are named in J.J. Dennis' honor.
