A new episode of Research Rabbit Hole, our Facebook Live show, premiered Monday evening, June 14, at 9 p.m. ET.

Season 1, Episode 11, begins in London in 1855, and travels back in time to the origins of photography and the great Daguerre. But he’s not the only mover and shaker who influenced “sun pictures” in the 19th century. In this episode, you’ll meet an inventor who dreamed of a different future for photography—and made it come true.

The full season is available on YouTube.

New episodes of Research Rabbit Hole premier every two weeks on our Facebook page. The host, Ronald S. Coddington, is Editor and Publisher of Military Images.
