Gesslein, George John, II

Lansing: George John Gesslein II, age 52, of Lansing, NY, was called home by the Lord on Sunday morning, February 24, 2013, at Cayuga Ridge Nursing Home in Ithaca, NY after a courageous 5 year battle with cancer. George was born just a few blocks away at the old Tompkins County Hospital on February 7, 1961, a son of George John Gesslein and Carol Lynne Gesslein (Mickelson). George was a self-taught computer programmer who worked for a number of local firms and ultimately set his sights on creating a really good algebraic manipulation program to solve difficult math equations. From this effort was born "Mathomatic", an easy to use math program that is now available in many forms and is in use throughout the world ( Survivors include his parents, Carol and George Gesslein of Lansing, NY; his four siblings, Lisa L. Wheeler, (Mark) of Lansing, NY, Laura L. Gesslein (Tim Holloway) of Williams, OR, Karl D. Gesslein of Wilseyville, NY, and Paul M. Gesslein of Ithaca, NY.
