Obituary Condolences

Passed away peacefully on the morning of March 29, 2013. He was born in Braddock, PA on January 31, 1934, to Mary and Michael Seman. He had two younger siblings, Michael Seman and Marlene Smith. In the mid 1950's he enlisted in the Army and due to test placements was transferred to White Sands Proving Ground, NM, to begin the guided missile propellant school. It was here that his long and distinguished career in rocketry began. Upon being discharged from the Army he enrolled in the University of Pittsburgh, and graduated in 1959 with a B.S. in Chemical Engineering. In 1960 he began his lifelong career at Allegany Ballistics Laboratory (ABL), Hercules, Inc., in Rocket Center, WV. He began as a design engineer. In 1962 his office moved to Cape Canaveral, FL, where he served as the representative for Hercules at the Naval Weapons Station. From 1963-1967 his office was transferred to Lockheed Missile and Space Company in Sunnyvale, CA. In 1967 he was transferred to the Bacchus Works plant outside of Salt Lake City, UT. It was here he started a family. He was involved in many rocket programs at Hercules, including the Nike, Minuteman, and Pershing II. Highlighting his career he was the Manager of Trident-I (C-4) Third Stage, and Program Manager Trident-II (D-5), the chief missile of America's current submarine-launch nuclear deterrent. In 1987 he became the Program Director of Titan IV, at that point the largest American engineered rocket ever produced. He was transferred back to Cape Canaveral, FL in 1993 where he oversaw the Titan IV program, and he retired in 1995. He was an avid lover of all things nautical and aviary, in addition to rocketry and space. There wasn't a plane, boat or submarine he didn't know the name of. He enjoyed golfing, hockey, hiking, attending the symphony, and studying history. He lived an eccentric lifestyle and enjoyed collecting gadgets amongst other things. Yet amongst all his success and many intense interests, it was his family he loved above all else. He is profoundly missed by his three surviving children, Jill, Janet, and Michael Seman. He is also survived by his grandchildren Alex and Mary (to Jill Seman and Mike Coleman), Olivia and Haley (to Janet Seman and Tim Corey), and Soren (to Michael Seman and Ashley Murphy), as well as his sister Marlene Smith. A memorial will be held on April 19th from 1-5 p.m. at Hiller Aviation Museum in San Carlos California: 601 Skyway Rd. San Carlos, CA 94070, (650) 654-0200. SEQUIM VALLEY FUNERAL CHAPEL is in charge of arrangements. Please leave condolences at:
