CRYSTAL LAKE – Philip L. Koltun, 61, of Crystal Lake, passed away Friday, Oct. 26, 2012, at Northwestern Memorial Hospital in Chicago from acute myeloid leukemia.
He was born May 6, 1951, the second son of Abraham and Rhoda (Rosenzweig) Koltun. An excellent student, Phil graduated from high school at age 16 and began his undergraduate studies in computer science at the University of Illinois in Champaign-Urbana. He went on to obtain a master's degree in computer science from Carnegie-Melon University in Pittsburgh and a Ph.D. in computer science from the University of North Carolina in Chapel Hill. His academic career included teaching computer science at North Carolina State University and Sangamon State (now UI-Springfield).
Phil left academia for industry in 1983 and worked for Harris Corporation in its software operations division and eventually in engineering productivity at the corporate headquarters.

Phil met his future spouse, Patricia Melcher, while working at Harris. They married Nov. 4, 1989, in Indiatlantic, Fla. They had two sons, Alex and Andrew. Phil was first and foremost a very loving and giving family man dedicated to his sons and wife. He took great joy in nurturing and encouraging their passions, academic and occupational interests.
