Dagron & Cie (active 1860s)
Artist associated with 1 portrait
Born in Beaumont, France, in 1819, René Patrice Proudhon Dagron was a chemist by trade, but began taking portrait photographs in Paris in the 1860s. He was also well known for his microphotographic images, which he exhibited at the Académies des sciences. In the 1870s, during the Franco-Prussian War, Dagron became involved in helping to disseminate information among army officials. Using microphotography, he was able to publish extensive messages on prints small enough that carrier pigeons could handle several per flight. He died in 1900. The National Portrait Gallery holds one of his photographs.
