Human: Who invented the programming language called ‘lisp’? Assistant: 
Lisp was invented by John McCarthy in 1958. He was a professor at MIT, and he was trying to create a new programming language that would be easy to learn and use. He wanted the language to be easy to read and write, so he made it based on the idea of a list. A list is a collection of items, and each item in the list is separated by a comma.
