I interviewed Tom Kurtz in 2017. He was so generous, and as brilliant as you'd expect. He wrote me a memo on "Grammatical Simplifications in BASIC." He loved memos--was an academic mathematician at heart, even at 89! It was his idea to make computing accessible--he (modestly) credits Kemeny with all the other ideas about BASIC and the Dartmouth Time-Sharing System (DTSS). I wrote about the interview here: https://annettevee.substack.com/p/thomas-kurtz-basic-and-com.... The Birth of BASIC documentary that Dartmouth did for the 50th anniversary is excellent and features him prominently: https://youtu.be/WYPNjSoDrqw
