Samuel Johnson, often called Dr Johnson, was an English writer who made lasting contributions as a poet, playwright, essayist, moralist, critic, biographer, editor and lexicographer. He was a devout Anglican, and a committed Tory. The Oxford Dictionary of National Biography calls him "arguably the most distinguished man of letters in English history". James Boswell's Life of Samuel Johnson was selected by Walter Jackson Bate as "the most famous single work of biographical art in the whole of literature".
Born in Lichfield, Staffordshire, he attended Pembroke College, Oxford until lack of funds forced him to leave. After work as a teacher, he moved to London and began writing for The Gentleman's Magazine. Early works include Life of Mr Richard Savage, the poems London and The Vanity of Human Wishes and the play Irene. After nine years' effort, Johnson's A Dictionary of the English Language appeared in 1755 with far-reaching effects on Modern English, acclaimed as "one of the greatest single achievements of scholarship". Until the arrival of the Oxford English Dictionary 150 years later, Johnson's was pre-eminent.
