Samuel Johnson (18 September 1709 [OS 7 September] - 13 December 1784), often referred to as Dr Johnson, was an English writer who made lasting contributions to English literature as a poet, playwright, essayist, moralist, literary critic, biographer, editor, and lexicographer. Religiously, he was a devout Anglican, [1] and politically a committed Tory. The Oxford Dictionary of National Biography describes Johnson as "arguably the most distinguished man of letters in English history".[2] He is the subject of James Boswell's The Life of Samuel Johnson, described by Walter Jackson Bate as "the most famous single work of biographical art in the whole of literature"
