Born July 18, 1921, in Gary, Ind., Evar graduated from Indiana University. Before resuming his studies, he had roles in the development and configuration of systems during World War II. He was among the earliest of his generation to receive a doctorate in mathematics from Princeton, which he did in 1948.
Evar taught at the University of Minnesota, the University of Arizona, and Arizona State University until his retirement in 1990. He worked as a mathematician with Goodyear Aircraft Corp. from 1953 to 1954.
Evar’s publications included Linear Algebra and Matrix Theory. Influenced by Princeton professor Albert Tucker *32, Evar produced his most notable work in mathematics: Linear Programs and Related Problems. Throughout his life he continued exploring many topics on his own, which included the all-important exponential function, a patent in linear programming (optimization) methods, and solutions for the Rubik’s cube of various dimensions.
Evar’s favorite types of exploration included traveling the Western outdoors, summers at the University of Colorado, and summiting the 14ers (peaks) of Colorado,
Evar is survived by his youngest daughter, Nancy Wood; and oldest son, Douglas Nering.
