Eclipses

The Harvard College Observatory participated in several eclipse expeditions in the 1800s and early 1900s. Many staff members used these opportunities to experiment with eclipse photography. The Plate Stacks is home to several collections of photographic glass plates featuring views of totality, as well as the Baily’s beads and diamond ring effects. Many of these photographs were taken in Shelbyville, Kentucky in 1869; Willows, California in 1889; Japan in 1887; Chile in 1893; and Washington, Georgia in 1900.
