content: Attempts to use computers to manipulate symbols as well as numbers date from the mid-1950s, with programs first published in the mid-1960s. George E. Collins (1928-2017), a computer science professor at the University of Wisconsin, introduced the program PM (Polynomial Manipulation) in 1966 and a system of Fortran programs known as SAC-1 (Symbolic and Algebraic Calculation) beginning in 1967. The topologist Robert F. Riley (1935-2000) of Binghamton University in New York used this documentation for SAC-1 in his studies of the polynomials associated with knots and links.
