‘Warts of All’ looks at the most famous biography in the English language, Boswell's Life of Johnson. Why did the life of such an eccentric, opinionated, neurotic 18th-century lexicographer, biographer, and journalist become the subject of the most famous biography? And why should such a disorganised, lengthy narrative become the model for biography? The ingredients to that success and lasting influence are examined in the context of the massive expansion of print and reading in Britain during the 18th-century. The complex portrait of the personality of Johnson was to have a profound influence on biographical writing.
