He married Yvonne Alexandrine Le Baron in 1900, and took the more French-looking name Coty, a variation on his mother's maiden name, when he moved to Paris.
He began by selling essences derived from flowers in Grasse, and then peddled his scents to the barbers of Paris. His genius, however, was in marketing and in recognizing that the bottle made the perfume. He had bottles designed by the great ceramist René Lalique. His first great successes were his Rose Jacqueminot scent, in a bottle by Baccarat, in 1904 and L'Origan in 1905. One of Coty's greatest success, Chypre (1917), gave its name to an entire fragrance family used in the industry's classifications.
Coty was something of a recluse, disliking crowds of any kind, and hiding behind his public image. The company he founded in 1904 is now Coty, Inc., based in New York City.
