    Biography

    Derrick Lehmer was known as Dick. His parents were Clara Eunice Mitchell and Derrick Norman Lehmer(often called DNL to distinguish him from his son DHL, or as we noted Dick). DNL was a professor of mathematics at Berkeley who was interested in number theory and mechanical computation. Eunice and DNL had five children so Dick grew up in a large family. He attended school in Berkeley but it was his father who had the greatest influence on him, and even at a very young age he became involved in his father's ideas in number theory and particularly his interest in constructing machines to assist with number theory calculations.
