Lee Felsenstein is an electronic design engineer known for his contributions to the early history of personal computing. Born
in Philadelphia, PA in 1945, Felsenstein studied electrical engineering and computer science at the University of California,
Berkeley, where he took part in the 1964 Free Speech Movement protests and was employed as a junior engineer at Ampex. Working
as a contract engineer since the 1970’s, much of Felsenstein’s output has focused on making personal computing more publicly
accessible. His contributions to the history of computing include designing the 1973 Pennywhistle modem, an early acoustic
coupler modem affordable to hobbyists, and the Osborne 1, the first commercially successful portable computer, released by
the Osborne Computer Corporation in 1981. Additionally, Felsenstein is known for co-founding the Community Memory Project,
a publicly-accessible computer bulletin board system self-branded as an “information flea market,” in 1973, and for his role
from 1975 to 1986 as moderator of the Homebrew Computer Club, a Silicon Valley-based group of computing enthusiasts whose
membership included Bob Marsh, Steve Wozniak, Adam Osborne, and Jerry Lawson, among others.
