Bibliography.About the Author
We are deeply saddened to learn of the death of noted author
W. Richard Stevens. His passing is obviously a tremendous
loss for the technical community, but it is a personal one for us
as well. Rich was both a gifted colleague and a valued friend who
will be greatly missed. We extend our sympathies to his family.
Obituary from the Arizona Daily Star:
STEVENS, W. Richard, noted author of computer books died on
September 1. He is best known for his "UNIX Network Programming"
series (1990, 1998, 1999), "Advanced Programming in the UNIX
Environment" (1992), and "TCP/IP Illustrated" series (1994, 1995,
1996). Richard was born in 1951 in Luanshya, Northern Rhodesia (now
Zambia), where his father worked for the copper industry. The
family moved to Salt Lake City, Hurley, New Mexico, Washington, DC
and Phalaborwa, South Africa. Richard attended Fishburne Military
School in Waynesboro, Virginia. He received a B.SC. in Aerospace
Engineering from the University of Michigan in 1973, and an M.S.
(1978) and Ph.D. (1982) in Systems Engineering from the University
of Arizona. He moved to Tucson in 1975 and from then until 1982 he
was employed at Kitt Peak National Observatory as a computer
programmer. From 1982 until 1990 he was Vice President of Computing
Services at Health Systems International in New Haven, CT, moving
back to Tucson in 1990. Here he pursued his career as an author and
consultant. He was also an avid pilot and a part-time flight
instructor during the 1970's.
He is survived by his loving wife of 20 years, Sally Hodges
Stevens; three wonderful children, Bill, Ellen and David; sister,
Claire Stevens of Las Vegas, NV; brother, Bob and wife Linda
Stevens of Dallas, TX; nieces, Laura, Sarah, Collette, Christy; and
nephew, Brad. He is predeceased by his parents, Royale J. Stevens
(1915-1984); and Helen Patterson Stevens (1916-1997). Helen lived
in Tucson from 1991-1997, and Royale lived here in the early 1930's
attending Tucson High School while his father was treated for TB at
the Desert Sanitorium (now TMC). The family asks that in lieu of
flowers, donations be made in Richard's name to Habitat for
Humanity, 2950 E. 22nd Street, Tucson, AZ 85713. A memorial service
for Richard will be held at St. Phillip's in the Hills Episcopal
Church on Tuesday, September 7th at 12:00 noon. Following the
service there will be a reception in the Murphy Gallery of the
Church. Please wear colorful clothing to the service; Richard loved
colors.
W. Richard Stevens was an acknowledged UNIX and
networking expert and the highly-respected author of several books.
He was also a sought-after instructor and consultant.
