Harper’s Bazaar (New York) : The first fashion magazine in the United States

Since its debut in 1867 as America's first fashion magazine, its pages have been home to talent such as the founding editor, author and translator Mary Louise Booth, as well as numerous fashion editors, photographers, illustrators and writers. Glenda Bailey is the editor-in-chief of U.S. edition of Harper's Bazaar.

Harper & Brothers founded the magazine. This company also gave birth to Harper's Magazine and HarperCollins Publishing.

Harper's Bazar began publication as a tabloid-size weekly newspaper catering to women in the middle and upper classes. It showcased fashion from Germany and Paris in a newspaper-design format. It was not until 1901 Harper's moved to a monthly issued magazine which it maintains today. Now Harper's Bazaar is owned and operated by the Hearst Corporation in the U.S. and The National Magazine Company in the U.K. Hearst purchased the magazine in 1913.
