Asher Peres (January 30, 1934 - January 1, 2005) was an Israeli physicist, considered a pioneer in quantum information theory. According to his autobiography, he was born in Beaulieu-sur-Dordogne in France, where his father, a Polish electrical engineer, had found work laying down power lines. Peres was given the name Aristide at birth, since the name his parents wanted to choose, Asher, the name of his maternal grandfather, was not on a list of permissible names. When Peres went to live in Israel, he changed his first name to Asher and his family name from Pressman to Peres.
