Mr. Sill served two years with the US Army 1954-1956, and worked on various engineering projects for General Electric (including space program Project Apollo). In late years he was Safety Engineer and Project Manager for the local Proctor & Gamble plant and once retired from P&G, worked as a consultant for N C Stauffer. He was an active member of the Osterhout Bible Church; served as an EMT and officer with the Tunkhannock Community Ambulance Association; and was a member of the Advisory Council behind the establishment of the County Emergency Communication system (9-1 -1). Mr. Sill was an Advanced Class Amateur Radio operator (KD3XR), amateur architect (designed the family home); and an amateur musician (harmonica).
