Did You Know?
In July 1946, a US Army–Navy task force detonated two thermonuclear bombs at Bikini, an atoll in the Marshall Islands in the Pacific Ocean, and the event dominated news around the world. A French designer, Jacques Heim, used the occasion to introduce a skimpy two-piece bathing suit dubbed l’atome, “the atom.” Another designer, Louis Réard, followed it up with an even smaller suit for which he registered the name bikini. It was first modeled by dancer Micheline Bernardini at a Paris fashion show on July 5. There is no solid evidence for why he gave this name to the suit, but it has since become an international word.
