According to the introducton "Lewis Theobald's edition of Shakespeare (1734) is one cornerstone of modern Shakespearian scholarshp and hence of English iterary scholarship in general." According to Wikipedia: "Samuel Johnson (often referred to as Dr Johnson) (18 September 1709 [O.S. 7 September] – 13 December 1784) was an English author. Beginning as a Grub Street journalist, he made lasting contributions to English literature as a poet, essayist, moralist, novelist, literary critic, biographer, editor and lexicographer. Johnson has been described as "arguably the most distinguished man of letters in English history" He is also the subject of one of the most celebrated biographies in English, James Boswell's Life of Samuel Johnson. Boswell's Life, along with other biographies, documented Johnson's behaviour and mannerisms in such detail that they have informed the posthumous diagnosis of Tourette syndrome (TS), a condition unknown to 18th-century physicians. He presented a tall and robust figure, but his odd gestures and tics were confusing to some on their first encounter with him." --This text refers to the Kindle Edition edition.
