Luis Walter Alvarez

13 June 1911 – 1 September 1988

Luis Walter Alvarez was an American experimental physicist who worked at the University of California, Berkeley for most of his career. He developed radar systems during the Second World War, took part in the Manhattan Project, and later used the hydrogen bubble chamber to discover a large number of short-lived particle resonances, work for which he received the 1968 Nobel Prize in Physics. With his son Walter he proposed that an asteroid impact caused the Cretaceous-Paleogene extinction.
