Samuel Johnson (18 September [O.S. 7 September] 1709 – 13 December 1784), often called Dr Johnson, was an English writer who made lasting contributions as a poet, playwright, essayist, moralist, literary critic, sermonist, biographer, editor, and lexicographer. The Oxford Dictionary of National Biography calls him "arguably the most distinguished man of letters in English history".
Born in Lichfield, Staffordshire, he attended Pembroke College, Oxford, until lack of funds forced him to leave. After working as a teacher, he moved to London and began writing for The Gentleman's Magazine. Early works include the poem London (1738), the biography Life of Mr Richard Savage (1744), the poem The Vanity of Human Wishes (1749) and the play Irene (1749). After nine years' effort, Johnson's A Dictionary of the English Language (1755) appeared and was acclaimed as "one of the greatest single achievements of scholarship". Later works included The History of Rasselas, Prince of Abissinia (1759) and The Plays of William Shakespeare (1765).
