Ron Hansen,

an American computer scientist and early computer chess programmer when he was undergraduate student at University of Waterloo in the mid 70s. Along with Jim Parry, Russell Crook, and Gary Calnek, he was co-author of the successful mainframe programs Ribbit [1] and its successor Treefrog [2], and wrote a master thesis on computer chess [3]. At his time at Waterloo, Jonathan Schaeffer benefited from the presence of Ron Hansen, who generously gave him a copy of Ribbit’s Fortran source code, which he used to learn how to write a chess program [4].
