I learned the Icon programming language as a grad student at UC Davis. Ron Olsen, then a new assistant professor had just gotten his Ph.D. from Arizona where Ralph Griswold, Icon's inventor taught and he brought it with him. Icon has a number of interesting programming language features. Griswold was also the inventor of SNOBOL. He died a few weeks ago. Computer Science has always been a discipline where the founders were still around. That's changing.
