He was born on June 1, 1940 in Taylor, son of the late Fred and Minnie Uritz Demech. He graduated from Pittston High School, Wilkes College, the Naval War College, and the National War College. Commissioned as Ensign in 1962, he served in the Navy for over 27 years, retiring in 1989. He was a career cryptologist and a qualified Surface Warfare Officer.
As a Navy Captain and Presidential Appointee, he twice served as the Executive Director for the President’s Foreign Intelligence Advisory Board (PFIAB) in the White House. For his service, he was awarded the nation’s highest peacetime military decoration, The Defense Distinguished Service Medal.
