Mill Creek resident David Lingle passed away on Wednesday, May 7th of lymphoma at the age
of 82. He is survived by his loving wife of 57 years, Linda, and their two sons, Nathan (Rachael)
and Matthew (Kathleen), and grandchildren Kelsey (Mandy) and Parker. Private services will be
held by the family.
Dave was born July 4th, 1942, in Cairo, Illinois, later living in East St. Louis. He enlisted in the
U.S. Army in the wake of the Cuban missile crisis, completing Special Forces training at Fort
Bragg in 1964 and serving in the 10th Special Forces Group.
After his honorable discharge, he attended Southern Illinois University in Edwardsville, where
he wrote and published poetry and began a lifelong fascination with mathematics. He earned a
Master of Arts in Mathematics in 1973. It was at SIUE that he met Linda and they were married
in 1968.
Dave continued to study mathematics at Dalhousie University in Halifax, Nova Scotia, then
taught at Bates College in Lewiston, Maine. Looking for a new direction, he earned a Masters
in Computer Science from SUNY Stony Brook in 1986. After teaching at Washington State
University in Pullman, Dave and his family relocated to Texas in 1990. There he began a long
career in software development.
In Texas, Dave worked for Convex Computer Corporation doing groundbreaking work in high
performance computing. He continued to work for Hewlett-Packard after it acquired Convex in
1995. Throughout his years in Texas he pursued a strong interest in bicycling, biking regularly
with the family on local trails, becoming involved in the bicycling community, helping scout new
trails, joining competitive races, and traveling to other states to join in large rides. He twice
completed the Hotter’n Hell Hundred, a 100 mile ride that takes place in August around Wichita
Falls, Texas.
In 1999, Dave and his family moved to the Pacific Northwest, where he worked the remainder
of his career using his broad knowledge of software development in supervisory roles for
several companies in Seattle. He continued to ride enthusiastically through the hills and
mountains of Washington State, including a strenuous group ride through the Cascades and
riding in the Seattle to Portland Classic. He also followed his lifelong pursuit of further
education, earning an MBA from the University of Washington in 2004.
Dave retired in 2013 to Mill Creek to study, ride his bicycles, listen to music, travel, follow
sports of all kinds, and hang out with family and friends. He enjoyed meeting people and
making new friends while working at a local market. He loved his Pomeranian, Sasha, spending
many happy hours indulging him.
Dave was a quiet, intelligent, thoughtful man with a subtle wit who provided a constant and
steadying presence to those around him, always willing to take time to listen or offer a
consultation or opinion when needed. His family and friends love and miss him.
