HISTORY
Logo was designed in 1967 by Wally Feurzeig, Seymour Papert and Cynthia Solomon at Bolt, Beranek and Newman in Cambridge, Massachusetts, as a language for teaching children to think like programmers. It is a dialect of Lisp, with lists and recursion at its core, but it is best known for turtle graphics: at MIT, children steered a small floor robot, the turtle, that drew lines with a pen as it moved. The name comes from the Greek "logos", meaning word or thought.
USAGE
Mostly educational and historic today. Logo is still used in some classrooms and hobbyist interpreters, and its ideas live on in Scratch, NetLogo and the turtle modules of other languages, such as Python's.
