QUOTE : After Bailey came Samuel Johnson, His Cantankerousness. Son of a London bookseller, a university dropout, afflicted with depression and what modern doctors think was likely Tourette’s—“a man of bizarre appearance, uncouth habits, and minimal qualifications”—Johnson was bewilderingly chosen by a group of English booksellers and authors to write the authoritative dictionary of English. Because of the seriousness of the charge, and because Johnson was scholarly but not a proper scholar, he began work on his dictionary the way that all of us now do: he read. He focused on the great works of English literature—Shakespeare, Milton, Dryden, Locke, Pope—but also took in more mundane, less elevated works. Among the books that crossed his desk were research on fossils, medical texts, treatises on education, poetry, legal writing, sermons, periodicals, collections of personal letters, scientific explorations of color, books debunking common myths and superstitions of the day, abridged histories of the world, and other dictionaries.
