 Johnson was a tall and robust man. His odd gestures and tics were disconcerting to some on first meeting him. 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, a condition not defined or diagnosed in the 18th century. After a series of illnesses, he died on the evening of 13 December 1784, and was buried in Westminster Abbey. In the years following his death, Johnson began to be recognised as having had a lasting effect on literary criticism, and he was claimed by some to be the only truly great critic of English literature.
