Ann Plato (c. 1823 – unknown)[1] was a 19th-century African American educator and author. She was the second African-American woman to publish a book in the United States and the first to publish a book of essays[1] and poems. As a young African-American girl writing in the 19th century, Plato has been described as an heir to Phillis Wheatley, who wrote her first published poem at the age of 13 in 1766.[2] There is little biographical information on Plato, and most of her life is known from her only published work, Essays; including Biographies and Miscellaneous Pieces, in Prose and Poetry, which included the preface written by Reverend James W. C. Pennington, an abolitionist leader in Hartford, Connecticut, and a pastor.[3]
