1. The name comes from the shape of the original store at 34 Boulevard St. Germain in Paris. The windows to the street formed a diptych and the founders thought they were being clever, throwing in some extra letters.
2. When it opened, in 1961, it was a kind of bazaar, selling random products from across the globe. But it was the fabrics–crazy ’60s prints on cotton–that finally put them on the map.
3. They’d paint the outside of the store a different color every week. It’s fuschia now, the last color chosen by the three founders, Christiane Gautrot, Yves Coueslant and Desmond Knox-Leet.
4. Their first candles, thé, hawthorne and cinnamon launched in 1963, but their original eau de toilette, which launched in 1968, was based off a potpourri recipe from the 16th century.
5. They’ve finally launched e-commerce. (Ok, so you might know that one, but just in case you missed it.)
