Vail Daily obituary: William Cohagan, 1945-2015

William L. Cohagan, 70, died in the early afternoon Wednesday. Born in 1945 in Fort Worth, Texas, Bill grew up in San Antonio and spent his adult life in Austin.

Bill attended the Culver Military Academy, where he was the captain of the Black Horse Troop. He built his first computer at the age of 13 and never stopped being delighted by programming. He received a BS in statistics from Stanford University and an MA in computer science from the University of Texas at Austin. He was instrumental in developing large-scale computers at Texas Instruments, contributing to innovations in parallel computing. His notes are viewable at the Computer History Museum in Mountain View, California. In 1993, he co-founded TeraQuest Metrics.

Bill loved classical music, tennis, science fiction, pugs, puns and his view of Lake Travis. He never met an event he couldn’t wear shorts to. He was incredibly generous with his time and spent hundreds of hours with family and friends solving IT problems that were way below his pay grade. He was unfailingly kind, honest and generous — a loving husband, father, grandfather and friend. He was a man who knew what brought him joy and, thankfully, he was surrounded by those things until the very end.

Bill is preceded by his parents, Stanley Robert Cohagan and Francis Sternenberg Cohagan, and his sister Judith Cohagan Fenyvessy. He is survived by his wife, Lynn Miller Cohagan; his sister Criswell Cohagan Gonzales; his daughter Carolyn Josephine Cohagan; his son Frederic William Cohagan; his daughter-in-law Tamsen Mann Cohagan, and his grandchildren; Liam and Kailen Cohagan.
