Mr. Leon Haig Assadourian July 2, 1941 – September 24, 2025
On the morning of September 24, 2025, Mr. Leon Haig Assadourian, age 84, went to be with his Lord and Savior, embarking from St. Augustine, Florida.
Leon was born in Harrisburg, Pennsylvania, and his family moved shortly after to a suburb of Philadelphia. He graduated as salutatorian from Sharon Hill High School in 1959. In the early years of his career, he served in the Navy (1963–1965) and then completed his education before becoming an Army Civilian in 1975.
He held a bachelor of science in Physics from the University of Illinois, a master's degree in physics from the University of Pennsylvania, and he finished a doctoral degree in electro physics from The Polytechnical Institute of New York.
He began government service when he was commissioned as an Ensign in the US Navy. He rose to the rank of First Lieutenant. He served for six months on the first nuclear powered submarine, the USS Nautilus. For a semester he taught physics at the United States Naval Academy. For the next year he had shore duty in the District of Columbia under the "Father of the Nuclear Navy", Admiral Hyman Rickover.
His Army Civilian career started in the Fire Control Division at Picatinny Arsenal, New Jersey. He transitioned during his Army Civilian career from optics to programming ballistic simulations. During this time he served as both an elder and a deacon in the church. One of his last projects was on the Army's guided mortar munition. He retired from the Ground Combat Simulation Team in 2009 at Picatinny Arsenal.
Leon led an active life in retirement. He was passionate about giving in terms of time, talents, treasure, and thoughts within his local churches in New Jersey, Virginia, and Florida, and to various other causes. He diligently maintained contact with family and friends, frequently attending large family reunions.
Leon was preceded in death by his loving wife of 45 years, Beth Assadourian.
He is survived by his loving and devoted children: son Charles "Chuck" Assadourian, of Lebanon, TN; his daughter, Laura Assadourian of St. Augustine, FL; daughter-in-law Dawn Assadourian of Lebanon, TN; his grandsons Tony Banks and Jonathan Assadourian; and his grand-daughter, Sarah Assadourian. His son and a grandson have followed a part of his life path through service in the military.
In accordance with Leon's wishes, a celebration of life was held at Covenant Presbyterian Church in St. Augustine, Florida.
The family extends their heartfelt thanks to Flagler Hospital in St. Augustine for the excellent care provided by compassionate caregivers, nurses, and doctors. Your support and kindness meant so much to the family during this time.
