BSD began as a fork of AT&T Unix, which AT&T had provided in source form to several universities. The University of California at Berkeley was one recipient, and their Computer Research Group produced a variant called BSD Unix that became popular in university and research environment. Bill Joy, later co-founder and VP of R&D at Sun Microsystems was chief architect of the BSD effort.
BSD was subsequently changed to include no AT&T code and released as open source, and several variants exist in current use.
