Harley Flanders (September 13, 1925 – July 26, 2013) was an American mathematician, known for several textbooks and contributions to his fields: algebra and algebraic number theory, linear algebra, electrical networks, scientific computing.^[1]

He received his bachelors (1946), masters (1947) and PhD (1949) at the University of Chicago on the dissertation Unification of class field theory advised by Otto Schilling and André Weil.^[2] He held the Bateman Fellowship at Caltech. He joined the faculty at University of California at Berkeley, then became professor at Purdue University (1960), and was with the faculty at Tel Aviv University (1970–77), visiting professor at Georgia Tech (1977–78), visiting scholar at Florida Atlantic University (1978–85), University of Michigan, Ann Arbor (1985–97, 2000–), University of North Florida (1997–2000) and, distinguished mathematician in residence at Jacksonville University (1997–2000).^[3] He was Editor-in-Chief, American Mathematical Monthly, 1969–1973. Flanders also wrote calculus software MicroCalc, ver 1–7 (1975–).^[4][5]

He died July 26, 2013.^[6]
