Howard Levi (November 9, 1916 in New York City – September 11, 2002 in New York City) was an American mathematician who worked mainly in algebra and mathematical education.[1] Levi was very active during the educational reforms in the United States, having proposed several new courses to replace the traditional ones.

Biography[edit]

Levi earned a Ph.D. in mathematics from Columbia University in 1942 as a student of Joseph Fels Ritt.[2] Soon after obtaining his degree, he became a researcher on the Manhattan Project.[3][4]

At Wesleyan University he led a group that developed a course of geometry for high school students that treated Euclidean geometry as a special case of affine geometry.[5][6] Much of the Wesleyan material was based on his book Foundations of Geometry and Trigonometry.[7]

His book Polynomials, Power Series, and Calculus, written to be a textbook for a first course in calculus,[8] presented an innovative approach, and received favorable reviews by Leonard Gillman, who wrote "[...] this book, with its wealth of imaginative ideas, deserves to be better known."[9][10]

Levi's reduction process is named after him.[11]

In his last years, he tried to find a proof of the four color theorem that did not rely on computers.[3]
