Dan Chess, a fellow classmate in the Columbia Science Honors Program, recalls Richard Stallman seeming a bit weird even among the students who shared a similar lust for math and science. "We were all geeks and nerds, but he was unusually poorly adjusted," recalls Chess, now a mathematics professor at Hunter College. "He was also smart as shit. I've known a lot of smart people, but I think he was the smartest person I've ever known."

Another favorite maternal anecdote dates back to the early 1960s, shortly after the puzzle incident. Around age seven, two years after the divorce and relocation from Queens, Richard took up the hobby of launching model rockets in nearby Riverside Drive Park.
