LOGO

A Lisp-like language for teaching programming, noted for its "turtle graphics" used to draw geometric shapes. LOGO was developed in 1966-1968 by a group at Bolt, Beranek & Newman (now "BBN Technologies") headed by Wally Fuerzeig <fuerzeig@bbn.com> (who still works there in 2003) and including Seymour Papert <seymour@media.mit.edu>.
