Butler Lampson

Why Alto. Lampson's 1972 memo made the case for giving every researcher a computer of their own, and he designed much of the Alto's system software. With Charles Simonyi he built Bravo, the first editor to show text on screen as it would print, and he worked on the software for PARC's laser printers and networks. His principles of system design are still taught. He received the Turing Award in 1992.
