John Baron (physician)

He then attended a patient in Lisbon for two years, and on his return settled in practice at Gloucester.

He lived at Cheltenham during the rest of his life, disabled by ‘creeping palsy’ during his later years.

[1] Among his friends were Dr. Matthew Baillie, who had a country house in the Cotswolds, near Cirencester, and Edward Jenner, who practised in the Vale of Berkeley, on the other side of the hills, sixteen miles from Gloucester.

The theory of tubercles, from Jenner and earlier John Hunter, later ran out as misleading;[1] it had opponents in Gaspard Laurent Bayle, René Laennec, and François-Joseph-Victor Broussais.

[2] Dupuy, a French veterinarian, had been led two years earlier (1817), and independently of Baron, to adopt the same hydatid theory, to explain the hanging ‘pearls’ or ‘grapes’ that are a common form of tubercle in cattle.
