Harvey C. Nathanson

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.

Mario Refice

Computer scientist

Life member, 78; died 20 December

Refice conducted research on experimental-systems automation, software engineering, and computer-assisted instruction. He was the principal investigator for several European-funded research projects involving speech and language processing and human-machine interaction.

He received a bachelor’s degree in physics in 1967 at the University of Bari Aldo Moro, in Italy. After graduating, he worked as a technician in the university’s high-energy physics laboratory.

He left in 1970 to join Centro Studi e Applicazioni Tecnologie Avanzate, a research consortium in Bari. At the time, he was also a visiting researcher at the University of Texas at Austin and Stanford. While at Stanford, he collaborated with other researchers to adapt the TENEX operating system to the Digital Equipment Corp.’s PDP-10 computer.

In 1981 he began teaching advanced courses in computer science for the UNESCO Intergovernmental Bureau of Informatics in Ghana, Guinea, and other countries. He also was a scientific consultant for the Royal Scientific Society, in Amman, Jordan.

He took a permanent position in 1985 as an associate professor of computer science at the University of Bari Aldo Moro.

He left in 1991 to join the Polytechnic University of Bari, where he taught undergraduate and graduate courses in computer science. Even after his retirement in 2011, he taught and conducted research projects at both Bari universities.

Herbert Bernhardt Voelcker Jr.

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.

In 1958 he received a two-year Fulbright fellowship, which enabled him to study at the Imperial College in London, where in 1961 he earned a Ph.D. in electrical engineering.

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.

Eric Sacher

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.

Walter Kurt Kahn
