In 1906, Daltroff met Félicie Wanpouille (1874-1967), a young milliner who also worked on rue de la Paix, she introduced him to her clients, and soon became his business partner and muse.

First created in powder form, the perfume N'Aimez Que Moi was launched in 1917, designed for young women waiting for the return of their beloved who had gone to war.

In 1934, at a time when men mainly used colognes, Daltroff, who was always convinced that a man should wear perfume, boldly launched a masculine fragrance Pour un homme.

[5] After World War I, in 1918, Ernest Daltroff was invited to the Bronx International Exposition of Science, Arts and Industries in New York with his competitor François Coty, where he won the prize for the most go-ahead company, opening up the American market for him for the Interwar period.

During the German military administration in occupied France during World War II, the company was heavily taxed and in 1941, Caron risked spoliation.

As soon as the war ended, Félicité Wanpouille, who ran the company with her husband Jean Bergaud and perfumer Michel Morsetti trained by Daltroff, moved Caron to sumptuous quarters decorated by Maison Jansen at 10 Place Vendôme.

President Jean-Paul Elkann sold the salons on Place Vendôme and trivialised the brand, which nevertheless remained in French hands in spite of an offer to purchase 80,000 shares by Robins of Richmond, Virginia.
