In Memoriam: Sir Aaron Klug

MSA announces with regret the passing of Sir Aaron Klug on November 20, 2018, at age 92. Klug was born in Lithuania, but grew up in South Africa. He received the Nobel Prize in chemistry in 1982 for the development of electron crystallography. After early work in metallurgy at Cambridge, in the 1950s and 1960s, he worked with Rosalind Franklin on the structure of Tobacco Mosaic Virus (TMV), and then worked on viruses with Kenneth Holmes and John Finch. He joined the MRC lab in Cambridge in 1962, and he was knighted in 1988. In 1970, his work with DeRosier and Crowther on 3-D reconstruction from projections resulted in a landmark paper in structural biology. MSA recognizes many Nobel prizes having been awarded to both light and electron microscopists.
