Edwin Ernest Salpeter ForMemRS (3 December 1924, Vienna – 26 November 2008,Ithaca, New York) was an Austrian–Australian–American astrophysicist.
Born to a Jewish family, Salpeter emigrated from Austria to Australia while in his teens to escape the Nazis. He attended Sydney Boys High School (1939–40) and Sydney University, where he obtained his bachelor's degree in 1944 and his master's degree in 1945. In the same year he was awarded an overseas scholarship and attended the University of Birmingham, England, where he earned his doctorate in 1948 under the supervision of Sir Rudolf Peierls. He spent the remainder of his career at Cornell University, where he was most recently the James Gilbert White Distinguished Professor of the Physical Sciences, Emeritus. Salpeter died of leukemia at his home in Ithaca on November 26, 2008.
In 1950 he married Miriam (Mika) Mark (1929–2000), a neurobiologist born in Riga, Latvia; she was chairwoman of the department of neurobiology and behavior at Cornell from 1982 to 1988. The Society for Neuroscience created the Mika Salpeter award in her memory; it "recognizes an individual with outstanding career achievements in neuroscience who has also significantly promoted the professional advancement of women in neuroscience." The Salpeters had two daughters, Judy Salpeter and Dr. Shelley Salpeter.
In 1951 Salpeter suggested that stars could burn helium-4 into carbon-12 with the Triple-alpha process not directly, but through an intermediate metastable state of beryllium-8, which helped to explain the carbon production in stars. He later derived the initial mass function for the formation rates of stars of different mass in the Galaxy.
