IEEE Medal of Honor and National Medal of Science recipient
Nonmember, 95; died 6 July
Quate received the 1988 IEEE Medal of Honor for the invention and development of the scanning acoustic microscope. The device uses high-frequency sound waves to apply gentle pressure to objects under observation, allowing for new measurements of the internal structures, density, elasticity, and viscosity of living cells without harming them.
He also received the U.S. National Medal of Science in 1992, given to him by President George H.W. Bush, for his contributions to engineering science.
Quate started his career in 1950, when he began working on microwaves as part of the technical research staff at Bell Telephone Laboratories, now Nokia Bell Labs, in Murray Hill, N.J. He was later promoted to associate director of electronics research there. He left in 1959 to work for Sandia Corp., now known as Sandia National Laboratories, in Livermore, Calif., serving as part of the technical research staff. He was promoted the following year to vice president and director of research.
In 1961 he joined Stanford as a professor of applied physics and electrical engineering, eventually becoming a department chair, and remained there until his retirement.
Quate earned a bachelor’s degree in in 1944 in electrical engineering from the University of Utah in Salt Lake City. After graduating, he was selected to work at the Oak Ridge National Laboratory in Tennessee as part of the Manhattan Project. In 1950, Quate also earned his Ph.D. in electrical engineering from Stanford.
Game theorist and coding pioneer

Berlekamp was a professor of mathematics, electrical engineering, and computer science at the University of California, Berkeley. He left there briefly in 1967 to work for Bell Telephone Laboratories, in Murray Hill, N.J., but returned to UC Berkeley in 1971. Berlekamp worked at the university part-time in order to focus on his company, Cyclotomics, based in Oakland, Calif. He founded the company in 1973 and retired from there in 2006.
The company’s bit-serial encoders, which convert information from one format to another, and Berlekamp decoders, devices named after him that were capable of converting audio or video signals into different forms, such as analog, became the standards used in NASA’s space communications programs. Both types of devices are still operating on the Voyager I and II satellites, launched in 1977.
In addition, Berlekamp invented several algorithms. The Berlekamp polynomial-factoring algorithm was the first technique for finding solutions for large polynomial equations used in coding. It’s still used in cryptography. Berlekamp was also the coinventor of the Berlekamp-Welch algorithm and the Berlekamp-Massey algorithms, both used for efficient decoding of Reed-Solomon codes. Berlekamp also discovered an algorithm for factoring polynolmials over finite fields, included in computer algebra systems such as Pari.
He coauthored the two-volume set, Winning Ways for Your Mathematical Plays. Berlekamp also wrote the seminal book Algebraic Coding Theory, published in 1968.
In 2013, Berlekamp and his wife, Jennifer, founded the Elwyn and Jennifer Berlekamp Foundation, which supports math and science outreach and educational programs, especially those focusing on combinatorial game theory.
Berlekamp was also a member of the American Academy of Arts & Sciences, the American Association for the Advancement of Science, the American Mathematical Society, the National Academy of Engineering, and the National Academy of Sciences.
He received numerous honors, most notably the 1993 IEEE Claude E. Shannon award. Other IEEE awards he received include the 1990 IEEE Koji Kobayashi Computers and Communications Award and the 1991 IEEE Richard W. Hamming Medal.
Berlekamp earned both a bachelor’s and master’s degree in electrical engineering in 1962 and a Ph.D. in electrical engineering in 1964, all from MIT.
