Wallace "Wally" Feurzeig (June 10, 1927 – January 4, 2013)[1] was an American computer scientist who was co-inventor, with Seymour Papert and Cynthia Solomon, of the programming language Logo,[3] and a well-known researcher in artificial intelligence (AI).

His colleagues were actively engaged in some of the pioneering AI work in computer pattern recognition, natural-language understanding, automated theorem proving, Lisp language development, and robot problem solving.

Much of this work was done in collaboration with distinguished researchers at the Massachusetts Institute of Technology (MIT) such as Marvin Minsky and John McCarthy, who were regular BBN consultants during the early 1960s.

Some of the first work on knowledge representation and reasoning (semantic networks), question answering, interactive computer graphics, and computer-aided instruction (CAI) was actively underway.

Shortly after TELCOMP was created, Wally decided to introduce it to children as a tool to teach mathematics and in 1965–66, under U.S. Office of Education support, explored its use as an auxiliary resource in eight elementary and secondary schools served by the BBN time-sharing system.

Wally's collaborators in this research were Daniel Bobrow, Richard Grant, and Cynthia Solomon from BBN and consultant Seymour Papert, who had recently arrived at MIT from Jean Piaget's Institute in Geneva.
