HIGHLIGHTS ADVANCED MATERIALS & PROCESSES | MAY/JUNE 2024 62 IN MEMORIAM Richard R. Langhoff, 88, of Mattapoisett, Massachusetts, died on April 25. Born in Pittsburgh, he was a graduate of Langley High School (1953) and the University of Pittsburgh, School of Engineering (1964). Langhoff was a Vietnam veteran and trained as a U.S. Air Force pilot through the Aviation Cadet program. He began his work career as a technician at Westinghouse Electric’s Bettis Atomic Power Laboratory, builders of nuclear reactors for the first nuclear submarine named Nautilus, the first commercial nuclear power station at Shippingport, Pennsylvania, and the first nuclear powered aircraft carrier, Enterprise. At Bettis, he worked his way through college, but interrupted his education with an enlistment in the U.S. Air Force. Upon graduation with a B.S. in metallurgical engineering, he worked as a metallurgist for a number of companies. He retired from Raytheon’s Integrated Defense Systems, Portsmouth, Rhode Island, as a principal systems engineer in 2002. He also was a professional engineer in Massachusetts and did part-time consulting after retirement. Langhoff taught metallurgy courses for ASM International. He was a Life Member of ASM and also once served nationally as ASM’s Membership Committee secretary. He was a past member of the American Welding Society, the International Metallographic Society, the Fabricators and Manufacturer’s Association International, and the American Society for Testing Materials. He held one U.S. patent and authored over 800 technical reports and seven technical publications. David Sapiro, 33, of Seattle, passed away on August 31, 2023. Sapiro was a senior materials engineer at Ultra Safe Nuclear Corp. (USNC), where he was responsible for the materials selection for structural and function components in multiple systems including nuclear thermal propulsion and surface power generation. Prior to USNC, he was a materials engineer for the Naval Surface Warfare Center Indian Head Division. While in that role, he received the division’s Safety Excellence Award in 2018. Sapiro also had experience as a materials scientist in pursuing a patent in metal additive manufacturing processing. He earned a master of science degree in materials science and engineering (MSE) from the University of Washington, followed by a Ph.D. in MSE from Carnegie Mellon University (CMU). During his time at CMU, he held a postdoctoral researcher post with the National Energy Technology Laboratory. For more than nine years, he served as a student supervisor with Engineers Without Borders helping to develop methods to convert plastic beverage containers to thatching materials for developing countries. Sapiro received a Safety Excellence Award in 2018 from the Naval Surface Warfare Center Indian Head Division and most recently served as chair of the ASM Archaeometallurgy Technical Committee.
