Dr. John Orehotsky

July 24, 1934 — March 23, 2022

Dr. John L. Orehotsky, 87, Dallas, passed away, Wednesday, March 23, 2022 at Greenbiar in Dallas. Born in Hartford Connecticut, he was the son of the late Louis and Irene Bernath Orehotsky and was a graduate of Windham High School.  He continued his education at the Massachusetts Institute of Techology (MIT) with a B.S. in Metallurgy.  He followed that with an M.S. from Brooklyn Polytechnique Institute, and finally received his PhD from Syracuse University in Solid State Physics.

Dr. Orehotsky served as a professor with Wilkes University until his retirement. During his tenure as a professor, he received two Fulbright Scholarships, one to Porto, Portugal in 1981 and a second to Bratislava in the former Czechoslovakia in 1987.  Additional research fellowships received included Dalhousie University in Halifax, Nova Scotia, Canada; Brookhaven National Laboratories in Upton, Long Island, New York; The Jet Propulsion Laboratories (JPL) in Pasadena, California; and the Solar Energy Research Institute (SERI) in Boulder, Colorado.   He was an avid reader, and historian. He attended The Community Bible Church, Tunkhannock.

Among John’s greatest passions was time with family.  He was preceded in death in August 2021 by his wife of sixty-five years the former Ruth Ann Larsen; and his brother, Richard Orehotsky in May 2017. Surviving are his daughter, Jennifer Whisenhant and her husband Gregory, Fairbanks, Alaska; sons, John Orehotsky and his wife Nicole, Gilbertsville, Pennsylvania, and David Orehotsky and his wife Deborah, Dallas, Pennsylvania; nine grandchildren and two great grandchildren; brother, Norman Orehotsky.
