About the author
Born in Sarthe, France, in 1819, this early pioneer of photography studied physics and chemistry in Paris before moving into photographic work and invention. He is best remembered for receiving the first patent for microfilm in 1859, a breakthrough that showed how large amounts of information could be reduced to an extremely small scale.
He also became known for popularizing tiny photographic images viewed through small optical lenses, often called Stanhopes. These novelty objects mixed science, craftsmanship, and entertainment, and they helped make his name widely recognized in the 19th century.
Dagron's work took on real historical importance during the Siege of Paris in 1870–71, when microphotography was used to send messages by carrier pigeon. That combination of technical skill and practical imagination makes him an especially interesting figure in the story of photography and communication.
