History Jean Prouvost created the first ion in 1937, which is distributed each Wednesday. French readers flocked to newsstands to buy this early weekly ion, which was a resounding success. As is known, in 1942, the German occupation authorities in France stopped the distribution of most magazines, and Marie Claire was one of them. The magazine was not redistributed until 1954. At that time, became a monthly, against the original version, a weekly one. In 1976, Prouvost retired and his daughter velyne the magazine and added L’Oreal Group to the company. Evelyne Prouvost died recently. Marie Claire is now part of Hearst Corporation, headquartered in New York. Hearst has offices in France, Italy, and in several locations in the United States such as Detroit, the West Coast, New England, the Midwest, the Southwest and the Southeast.
