 Its appearance was similar to that of a finger wave, but made by a quite different means.

 In their return in the 1990s, the style was popularized by Hip Hop stars of the time, specifically Missy Elliot.
 The popularity of finger waves in the 1990s was aided by a movement toward shorter, more natural hair in the African-American community.

 In World War II he was a double agent for the French Resistance and part of the Marco Polo Network.
 He ran the Demographics Department ("Service de la démographie") of Vichy which soon through a merger with the SGF (General Statistics of France) became the new National Statistics Service, which he continued to head up.
 In this capacity, he sabotaged the Nazi census of France, saving untold numbers of Jewish people from death camps.
 The IEEE newspaper, "The Institute", describes Carmille as being an early ethical hacker: "Over the course of two years, Carmille and his group purposely delayed the process by mishandling the punch cards.
 He also hacked his own machines, reprogramming them so that they’d never punch information from Column 11 [which indicated religion] onto any census card."
 He also used his department to help mobilize French resistance in Algeria.
