The 84 Year Old Virgin
Yep, Sir Isaac Newton (1643-1727) never had sex. There is little documentation in any of his biographies of a relationship with another woman, except for that of his mother, and that of his 8 year old niece.
Newton was blisteringly Protestant, and would not have considered sex without marriage first. But he was too busy with mathematics, religion, and all-around mental stuff to bother mixing up with some woman.
