William Tyler Olcott (January 11, 1873–July 6, 1936) was an American lawyer and amateur astronomer. He was born in Norwich, Connecticut, to William Marvin Olcott and E. Octavia Tyler, and was educated at Trinity College at Hartford, then attended law school in New York. Although admitted to the bar in New York and Connecticut, he never practiced law. In 1902, he was married to Clara Hyde. During 1905 while vacationing in Rhode Island, a friend of Clara introduced him to the stars and constellations. He was instantly enthralled, and two years later had published his first book, A Field Book of the Stars. In 1909, after attending a lecture by Edward Charles Pickering, he developed an interest in observing variable stars. In 1911, he co-founded the American Association of Variable Star Observers (AAVSO). Olcott also wrote six books to popularize the field of amateur astronomy.
