Anna Wintour [SEP] Introduction
Dame Anna Wintour (; born 3 November 1949) is a British-American journalist and editor who has been editor-in-chief of "Vogue" since 1988 and artistic director for Condé Nast, "Vogue"s publisher, since 2013. With her trademark pageboy bob haircut and dark sunglasses, Wintour has become an important figure in much of the fashion world, widely praised for her eye for fashion trends and her support for younger designers. Her reportedly aloof and demanding personality has earned her the nickname "Nuclear Wintour". Her father, Charles Wintour, editor of the London "Evening Standard" (1959–1976), consulted her on how to make the newspaper relevant to the youth of the era.
