Keith Bostic is an American software engineer and one of the key people in the history of Berkeley Software Distribution (BSD) Unix and open-source software. In 1986, Bostic joined the Computer Systems Research Group (CSRG) at the University of California, Berkeley. He was one of the principal architects of the Berkeley 2BSD, 4.4BSD and 4.4BSD-Lite releases. Among many other tasks, he led the effort at CSRG to create a free software version of BSD Unix, which helped allow the creation of FreeBSD, NetBSD and OpenBSD. Bostic was a founder of Berkeley Software Design Inc. (BSDi), which produced BSD/OS, a proprietary version of BSD. In 1993, the USENIX Association gave a Lifetime Achievement Award (Flame) to the Computer Systems Research Group, honoring 180 individuals, including Bostic, who contributed to the group's 4.4BSD-Lite release. Bostic and his wife Margo Seltzer founded Sleepycat Software in 1996 to develop and commercialize Berkeley DB, an open-source, key-value database. Sleepy
