David P. (David Peck) Todd

David Peck Todd (1855–1939) was an American astronomer whose career combined patient observation with a taste for adventure. After studying at Amherst College, he returned there in 1881 as an instructor in astronomy and director of the observatory, a role he held for decades.

He became especially well known for organizing expeditions to observe solar eclipses around the world and for his work with astronomical photography. One of his best-known achievements was producing a complete set of photographs of the 1882 transit of Venus, a major scientific event of the era.

Todd’s papers and later historical accounts also show how wide-ranging his interests were: teaching, lecturing, travel, instrumentation, and sharing astronomy with the public. He spent much of his professional life in Amherst, Massachusetts, and remains remembered as one of the college’s notable scientific figures.
