After earning his Ph.D. in 1977, Marlow Anderson taught at Indiana-Purdue University in Fort Wayne before coming to Colorado. His graduate work at the University of Kansas was in algebra, specifically lattice ordered groups, and he maintained his interest and research momentum when he joined the department at Colorado College in 1982. Anderson has always had wide ranging interests in mathematics. Logic was an early fascination, geometry was one of the courses he enjoyed designing and teaching, and the history of mathematics became a strong interest.
