Louis Aucoc (21 September 1850 Paris - 10 December 1932 Paris), was a leading Parisian art nouveau jeweller and goldsmith, working with his father and brother André.
The Aucoc family firm at 6 Rue de la Paix was established in Paris in 1821[1] and was patronised by the house of King Louis Philippe, the House of Orléans, Napolean III and Empress Eugenie.
From 1874 to 1876, René Lalique was an apprentice to Aucoc. Lalique would later become a defining figure in the art nouveau movement.
The business left the hands of the Aucoc family in 1932.
Louis Aucoc married Micheline Louise Isaiah Rondeleux on 4 June 1872 [2] and had three children - Georges, René and a daughter who married André la Ferté.
