While North America is looking ahead to the total solar eclipse on August 21, it's also a good time to look back at another major date for such rarities: July 28, 1851. 

That's when Johann Julius Friedrich Berkowski took the first photograph of a total solar eclipse. The image was shot from a prime viewing spot at the Royal Observatory in Konigsberg in Prussia (now Kaliningrad in Russia).
