Bayard was persuaded to postpone announcing his process to the French Academy of Sciences by François Arago, a friend of Louis Daguerre, who invented the rival daguerreotype process.
In 1994, he was commissioned by the Arago Association to create a memorial to the French astronomer François Arago, known as Hommage à Arago.
On the 19th of August 1839 at the French Academy of Sciences, François Arago publicly unveiled the previously secret details of the daguerreotype process, the first publicly announced photographic process.
