Microelectromechanical systems pioneer
Life Fellow, 83; died 22 November
Nathanson invented the first MEMS device, a tuner for microelectronic radios, in 1965 while working as an engineer at Westinghouse Research Labs in Pittsburgh.
While developing similar devices, Nathanson pioneered a method of batch fabrication in which layers of insulators and metal on silicon wafers are shaped and undercut through the use of masks and sacrificial layers. The process would become a mainstay of MEMS manufacturing.
Nathanson was granted a patent in 1973 for the use of millions of microscopically small moving mirrors to create a video display of the type now found in digital projectors.
Later in his career, he was involved in the development of monolithic microwave integrated circuits in gallium arsenide for airborne radar applications, concepts for atomic clocks, integrated circuits on coiled (curved) substrates and electronic system cooling ideas. He held more than 50 patents in the field of solid-state electronics.
He was promoted in 1988 to chief scientist at the Westinghouse Science and Technology Center, also in Pittsburgh. After his retirement in 2001, he consulted for Northrup Grumman in Baltimore.
He received a Ph.D. from Carnegie Mellon.

Research engineer and EE professor
Life Fellow, 90; died 23 January
After graduating from MIT in 1951 with a bachelor’s degree in mechanical engineering, Voelcker applied to the U.S. Army Signal Corps. He served as a signal officer in the 82nd Airborne Division for two years. Then he returned to MIT, where in 1954 he earned a master’s degree in electrical engineering.
The following year he began working as a research engineer at the Army’s Signal Labs in Fort Monmouth, N.J. He joined the Army Rifle team, which traveled to Melbourne, Australia, to represent the United States in the 1956 Olympic Games.
After returning to the United States, he became an assistant professor of electrical engineering at the University of Rochester, in New York state. In 1972 he founded the Production Automation Project, a research team at the university. Under his leadership, the team developed mathematical foundations and core algorithms for solid modeling—the enabling technology for modern mechanical computer-aided design.
In 1985 Voelcker became head of a new directorate for advanced manufacturing technologies at the National Science Foundation, in Washington. Less than a year later, the NSF went through a reorganization and Voelcker lost his position.
He became an EE professor at Cornell, retired in 2000, and was named professor emeritus.
Founder of Serendipity Systems
Life member, 80; died 30 January
During World War II, Sacher, who was a Russian refugee living in Shanghai, immigrated to Seattle with his family and joined the U.S. Air National Guard.
Sacher was a self-taught computer engineer who got his start fixing cash registers for software company NCR. While working there, he was granted three U.S. patents for his printed circuit board fault detection and isolation technology.
Sacherwent on to work as a manager in the marketing department of Cirrus Computers and Genrad Designs in Phoenix. In 1984 he founded Serendipity Systems, a software company, in Sedona, Ariz.
In his spare time, he loved to ski and fly model airplanes, and he was a ham radio enthusiast.

Kahn was born in Mannheim, Germany, and in 1938, he and his family fled to New York to avoid the Nazis.
He received a bachelor’s degree in engineering from the Cooper Union in New York. After earning his Ph.D. in electrical engineering from the Polytechnic Institute of Brooklyn, in New York, now the NYU Tandon School of Engineering, Kahn joined Wheeler Labs.
His teaching career began at the Polytechnic Institute, where he taught electrical engineering. He spent a year at the Office of Naval Research in London, then joined the faculty of George Washington University, in Washington, D.C., where he taught electrical engineering until he retired. While at the university, Kahn was chairman of the EE department and held a seat on the faculty senate.
He authored more than 100 papers in the fields of electromagnetics, microwave components, antennas, and optics. He served in several editorial roles with IEEE publications and was a longtime consultant for the U.S. Naval Research Laboratory in Washington.
