caption: HISTORY OF PHOTOGRAPHY Cover of the booklet "The mail through Piccioni Viaggiatori" by the French photographer, chemist and inventor Prudent Dagron (17 March 1819 - 13 June 1900). It describes the first practical application of microfilm: the process developed and patented by Dagron during the siege of Paris in 1870-71 to send copies of messages, on film to collodion, attaching them to the tail feathers of the pigeons travelers who came fly over the German lines, between Paris and the offices of the French government in Tours and Bordeaux. During the five months of siege hundreds of thousands of such films were sent. Paris, Typographie Lahure, 1871
