Jacques Guerlain
Jacques Edouard Guerlain (; 7 October 1874 – 2 May 1963) was a French perfumer, the third and most famous of the Guerlain family. One of the most prolific and influential perfumers of the 20th century, over eighty of Guerlain's perfumes remain known, though certain estimates suggest he composed some four hundred. Among his greatest fragrances are "L’Heure Bleue" (1912), "Mitsouko" (1919) and "Shalimar" (1925). Though his work earned him universal renown, a considerable fortune and honours such as that of Chevalier of the Legion of Honour, Guerlain avoided public attention, never once granting an interview. As a result, relatively little is known of his creative process or personal life.
