George E. Collins (January 10, 1928 in Stuart, Iowa – November 21, 2017 in Madison, Wisconsin)[1] was an American mathematician and computer scientist. He is the inventor of garbage collection by reference counting[G60][2] and of the method of quantifier elimination by cylindrical algebraic decomposition.[G75][3]
He received his PhD from Cornell University in 1955.[4] He worked at IBM, the University of Wisconsin–Madison (1966–1986) Ohio State University, RISC-Linz, Delaware University, and North Carolina State University.[1]
