According to his autobiography, he was born Aristide Pressman in Beaulieu-sur-Dordogne in France, where his father, a Polish electrical engineer, had found work laying down power lines. He was given the name Aristide at birth, because the name his parents wanted, Asher, the name of his maternal grandfather, was not on the list of permissible French given names. When he went to live in Israel, he changed his first name to Asher and, as was common among immigrants, changed his family name to the Hebrew Peres, which he used for the rest of his life.
