Raymond Augustin Mailhat

Raymond Augustin Jean-Baptiste Mailhat (28 March 1862 – 22 April 1923) was a French manufacturer of telescopes and precision optical instruments.

[2] After studying under Paul Gautier (1842-1909),[3] Raymond became the director of the Secrétan company’s optics workshop in Paris on 1 January 1889.

[2] The Maison Mailhat manufactured a wide variety of equipment for both scientists and amateurs:[4] The company furnished optical instruments to the Paris Observatory, the Faculté des Sciences de Paris, the Bureau des Longitudes, the Camille Flammarion Observatory in Juvisy, the Société Astronomique de France, French government ministries, several observatories in France and in other countries, meteorological stations, bridge and road engineers, railroads, and mines.

The Maison Mailhat and its fellow Paris-based competitors the Secrétan and Bardou companies were among the leading French precision optics manufacturers of the early twentieth century.

Ferdinand Quénisset used Mailhat lenses for early photographs of Mars in 1899 at the Camille Flammarion Observatory in Juvisy.
