History
Founded in 1898 by Albert Nelson Marquis as an American counterpoint to the UK-oriented publication of the same name (published by A.C. Black since 1849 and, notably, including substantial biographies since 1897), the first edition of the publication contained concise biographies of more than 8,500 "distinguished Americans". Albert Marquis wrote that the book's objective was to "chronicle the lives of individuals whose achievements and contributions to society make them subjects of widespread reference interest and inquiry."
Originally independent, it was acquired by the conglomerate ITT. News Communications, Inc., which owns The Hill, bought Marquis in 2003. In 2016, the company's assets, including all the trademarks were transferred to Marquis Who's Who Ventures LLC, which is privately owned.
