About the author

Born in London in 1764, John Haslam trained in medicine at the United Borough Hospitals and also attended medical classes in Edinburgh in the mid-1780s. He went on to serve for many years at Bethlem Hospital, where his day-to-day work gave him deep practical experience with patients then described as suffering from insanity.

Haslam wrote several influential medical works drawn from that experience. He is best known today for careful clinical descriptions of mental illness and for his case study of James Tilly Matthews, which later readers have often treated as an important early account in the history of schizophrenia. His books also give modern readers a striking picture of psychiatric practice in Britain at the turn of the nineteenth century.

His career was not without controversy: after a parliamentary inquiry into conditions at Bethlem, he lost his post in 1816. Even so, his writings remained important, and he is still remembered as a notable early medical writer on mental illness. He died in London in 1844.
