John H. Malmberg

John Holmes Malmberg (July 5, 1927 – November 1, 1992) was an American theoretical physicist who specialized in plasma physics.

Malmberg studied at Illinois State University (Bachelor 1949) and the University of Illinois at Urbana–Champaign (Master 1951), where he received his doctorate in 1957. From 1957 to 1969, he was a scientist in plasma physics at General Atomics. From 1967 until his death, he was a professor at the University of California, San Diego (UCSD).

In 1985, he received the James Clerk Maxwell Prize for Plasma Physics and in 1991 the American Physical Society's John Dawson Award for Excellence in Plasma Physics Research for his studies of non-neutral plasmas (such as gases from electrons).

Since 1993, the UCSD has awarded him the John Holmes Malmberg Prize in his honor.
