Richard Feynman
Feynman was born on May 11, 1918, in Queens, New York City, to Lucille , a homemaker, and Melville Arthur Feynman, a sales manager originally from Minsk in Belarus (then part of the Russian Empire). Both were Lithuanian Jews. They were not religious, and by his youth, Feynman described himself as an "avowed atheist". Many years later, in a letter to Tina Levitan, declining a request for information for her book on Jewish Nobel Prize winners, he stated, "To select, for approbation the peculiar elements that come from some supposedly Jewish heredity is to open the door to all kinds of nonsense on racial theory", adding, "at thirteen I was not only converted to other religious views, but I also stopped believing that the Jewish people are in any way 'the chosen people'". Later in his life, during a visit to the Jewish Theological Seminary, he encountered the Talmud for the first time and remarked that it contained a medieval kind of reasoning and was a wonderful book.
