Matthew Baillie

Matthew Baillie (27 October 1761 – 23 September 1823) was a British physician and pathologist, credited with first identifying transposition of the great vessels (TGV) and situs inversus.
Early life and education.
He was born in Shotts Manse in Lanarkshire, the son of Prof Rev James Baillie and Dorothea Hunter. His sister was the poet Joanna Baillie. He was a pupil of his uncle, the anatomist John Hunter and his father-in-law, Dr. Thomas Denman, a pre-eminent obstetrician in London at the turn of the nineteenth century, whose textbook on childbirth had been first published in 1788. Baillie was educated at the Old Grammar School of Hamilton (renamed the Hamilton Academy in 1848), the University of Glasgow, and obtained his MD from the University of Oxford in 1789, having been named Snell Exhibitioner in 1779.
Career.
On his death in 1783 his uncle William Hunter bequeathed him £5,000, his house in Great Windmill Street, plus the adjacent medical school and museum. Baillie taught at the school from 1783 to 1803. He then taught anatomy and was appointed Physician at St George's Hospital in 1789, but gave up both posts to establish his own medical practice in Grosvenor Square, becoming Physician in Ordinary to George III. He became Fellow of the Royal College of Physicians in 1790, specialising in morbid anatomy.
He was elected a Fellow of the Royal Society in 1790 and delivered their Croonian Lecture in 1791 (on the subject of muscles). He was also the second President of the Medical and Chirurgical Society of London 1808-1810.

His 1793 book, "The Morbid Anatomy of Some of the Most Important Parts of the Human Body," is considered the first systematic study of pathology, and the first publication in English on pathology as a separate subject.

The 1793 book went into multiple editions and was translated into numerous languages, and five editions were released in Britain before his death.
