Most famous as the writer of the first English Dictionary, which he wrote virtually single-handedly. The subject of Boswell's "The Life of Samuel Johnson," considered the greatest biography ever written. Everything he said was worth writing down, and Boswell did. Johnson was most influential writer of the 18th century and a supporter of many women writers, including Fanny Burney and Mary Wollstonecraft. If you put Johnson on your bumper next to Boswell, they will talk when no one is looking.
