Robert Albert Charles Esnault-Pelterie, pioneer of aeroplanes, engines, and rockets. He founded the Association des Industriels de la Locomotion Aérienne (Manufacturers Association of Aerial Locomotion) in 1908. His aircraft are numbered from 1907. He was generally working in or from Billancourt, France.

In 1904, Esnault-Pelterie built some unsuccessful versions of the Wright glider, including a vessel with ailerons.[1] Albert Francis Zahm (more charitable than Charles Harvard Gibbs-Smith) wrote that Esnault-Peletrie had a good design but should have purchased some of the key components from manufacturers who already specialized in making them.[2]

From 1907 to 1918, under designation REP, built at least 16 original designs including monoplanes, a floatplane, a parasol, and a fighter, some of which saw service in WWI. REP1 monoplane of 1907 with REP engine used wing warping. At Vickers request, sold REP license, 1911, to Vickers, which built eight REP monoplanes, 1911-1912. His firm was called Établissements Robert Esnault-Pelterie.

(We are missing a few pertinent Austrian patents here: basic ESNAULT-PELTERIE search. There are a few modest references to Belgian parental filings. Esnault-Pelterie was quite prolific. Filings in Spain seem to have greatly increased during his later productive years. These may not have been predominantly aeronautical. On the other hand, Patent ES-1907-40625 is absolutely aeronautical. There are others. We are working around various technical difficulties.)
