Jack W. Hollingsworth
Jack W. Hollingsworth RochesterJack W. Hollingsworth, 88, passed away September 26, 2012, in Rochester, NY of pneumonia. Born in South Haven, KS, he also lived in Caldwell, Kingman, and Wellington, KS, as job scarcity during the Great Depression necessitated frequent moves. As an undergraduate, Jack attended the University of Kansas, graduating in 1948 with a B.S. in engineering physics. In addition, in 1949, he received a B.A. in mathematics. While an undergraduate, he was commissioned as an officer to serve his country during World War II. He was a member of the U.S. Army Air Force from 1942 to 1945, serving overseas for approximately two years. During that time, he completed 33 bombing missions over Germany and Occupied France, a supply delivery mission to the Dutch resistance, and a mission to Kiev, Russia. His service earned him a Purple Heart, a Distinguished Flying Cross, and a number of other medals. On his return to the United States, he served as a navigation instructor for the Army Air Force. In 1951, Jack received an M.S. in mathematics from the University of Wisconsin, and in 1954 a Ph.D. in mathematics from the same university. A position at the main General Electric plant in Schenectady, NY moved Jack, his wife, Nancy and their infant son to New York State in 1954. In 1955, he set up the very first computer system used by the General Electric Company. From 1957 to 1979, Jack was a professor of mathematics and computer science at Rensselaer Polytechnic Institute (R.P.I.) in Troy, NY, directing the Computer Science Center until 1970. There was nothing he loved more than teaching and he was highly regarded by his students and other faculty. He was especially proud of being voted Meanest Man on Campus by R.P.I. students as part of a charity fundraiser. During these years, he served as a deacon at the Second Reformed Church in Schenectady, NY, and on the board of directors for BOCES in Saratoga, NY. In 1979, Jack and his wife, Nancy moved to Rochester, NY, where he taught mathematics and computer science at the Rochester Institute of Technology (R.I.T.) until his retirement approximately 16 years ago. From 1980 to 1982 he was director of the R.I.T. Computer Science Department. Jack's favorite past time was reading, frequently reading four biographies per week. During one summer break from classes, he set out to read 1,000 books and he accomplished this goal by summer's end! Jack was preceded in death by his son, Seth who passed away in 1974 at the age of 10. He is survived by Nancy, his wife of 62 years; his son, Joel Hollingsworth who resides in Scotia, NY with his wife, Kathy; his daughter, Priscilla Herzog who resides on the central coast of California with her husband, Daryl; and his sister, Donna June Lancaster, who resides in Texas. Jack was known for his honesty, hard work, and dedication to his students. He was friendly and outgoing and many will miss his bright smile. He loved the red barns of upstate New York and the wheat fields of Kansas.

I have very fond memories of Dr. Hollingsworth's lectures in "Scientific Applications Programming" at RIT. In addition to a great appreciation of APL, he provided us all with a living history of computer architecture, including firsthand descriptions of rotating drum and magnetic core memories. As a Computer Engineer, I still cherish these discussions. He was a great gentleman to one and all.

Rest in peace, JWH.
