A Conversation with Sam Leffler
James W. Russell · Queue · 2004
The seeds of Unix and open source were sown in the 1970s, and Sam Leffler was right in there doing some of the heaviest cultivating. He has been actively working with Unix since 1976 when he first encountered it at Case Western Reserve University, and he has been involved with what people now think of as open source, as he says, “long before it was even termed open source.” While working for the Computer Systems Research Group (CSRG) at the University of California at Berkeley, he helped with the 4.1BSD release and was responsible for the release of 4.2BSD. He has contributed to almost every aspect of BSD systems, most recently working (again) on the networking subsystem.
