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).[1][2]

In 1985, he received the James Clerk Maxwell Prize for Plasma Physics[3] and in 1991 the American Physical Society's John Dawson Award for Excellence in Plasma Physics Research[4] for his studies of non-neutral plasmas (such as gases from electrons).

Landau damping (collisionless damping) was first proved to exist experimentally by Malmberg and Wharton in 1964,[5] almost two decades after its prediction by Landau in 1946.[6]

In his honor, since 1993, UCSD has awarded the John Holmes Malmberg Prize to a graduating physics student with interest in experimental physics.[7]
