Dr. Marshall Kirk McKusick writes books and articles, teaches
classes on UNIX- and BSD-related subjects, and provides

and copyright issues particularly those related to operating
systems and filesystems. He has been a developer and commiter
to the FreeBSD Project since its founding in 1993. While
at the University of California at Berkeley, he implemented
the 4.2BSD fast filesystem and was the Research Computer
Scientist at the Berkeley Computer Systems Research Group
(CSRG) overseeing the development and release of 4.3BSD and
4.4BSD. He earned his undergraduate degree in electrical
engineering from Cornell University and did his graduate
work at the University of California at Berkeley, where he
received master's degrees in computer science and business
administration and a doctoral degree in computer science.
He has twice been president of the board of the Usenix
Association, is currently a member of the FreeBSD Foundation
Board of Directors, a member of the editorial board of ACM's
Queue magazine, a senior member of the IEEE, and a member of

In his spare time, he enjoys swimming, scuba diving, and
wine collecting. The wine is stored in a specially
constructed wine cellar (accessible from the Web at
http://www.mckusick.com/~mckusick/) in the basement of the
house that he shares with Eric Allman, his partner of
35-and-some-odd years and husband since 2013.
