by David P. (David Peck) Todd
Born in Lake Ridge, New York, in 1855, David Peck Todd studied at Columbia before graduating from Amherst College in 1875. He later returned to Amherst as professor of astronomy and became a central figure in the college's scientific life for decades.
Todd is best remembered for producing a complete set of photographs of the 1882 transit of Venus, a major astronomical event of his era. He also organized and joined numerous expeditions to observe solar eclipses in different parts of the world, combining research, travel, and public interest in astronomy.
He was married to writer and editor Mabel Loomis Todd, and their lives became closely connected with Amherst's intellectual and literary circles. David Peck Todd died in 1939, leaving a legacy as both a working astronomer and an energetic popularizer of science.
