Reanimating the 1882 Transit of Venus

  • In late 1882, Massachusetts astronomer David Peck Todd traveled to California to photograph the transit of Venus from the summit of Mount Hamilton, where a solar photographic telescope waited among the stacks of bricks and timbers from which Lick Observatory was rising.

  • As the transit unfolded on December 6th, Todd obtained a superb series of plates under perfect skies. His 147 glass negatives were carefully stored in the mountain vault, but as astronomers turned to other techniques for determining the scale of the solar system.
