The first successfully captured photograph of a total solar eclipse, this daguerreotype was shot on July 28, 1851, by Prussian photographer Johann Julius Friedrich Berkowski.
Here’s a little history lesson to help you pass the time between now and the next total solar eclipse on August 21st. The photograph above, a daguerreotype captured almost exactly 166 years ago, is the first successfully-captured photograph of a total solar eclipse.
The photo was captured by master daguerreotypist Johann Julius Friedrich Berkowski, a Prussian photographer who was commissioned by the Royal Prussian Observatory at Königsberg to do what nobody else had managed up until that point: capture an appropriately-exposed photograph of a total solar eclipse.
Up until that point, every photograph taken had been over or under-exposed, and/or didn’t capture sufficient contrast between the bright corona and the obscuring disk of the moon.
According to a paper in the journal Acta Historica Astronomiae, the photograph was captured using a small refracting telescope attached to the hour drive of the 15.8-cm Fraunhofer heliometer. Berkowski began exposing the image shortly after totality, and the final daguerreotype took 84-seconds to capture.
