Thomas Cogan was born in Rothwell, Northamptonshire on 8 February 1736 and died in London on 2 February 1818. He received his early education at Kibworth, in Leicestershire, and his preparation for the dissenting ministry at the academy at Mile End and at Homerton. In 1765, after six years in the ministry, he enrolled as a medical student at the University of Leiden, receiving the degree in 1767 with a dissertation, De animi pathematum, on the influence of the human passions on disease. For the next thirteen years, Cogan practised as a physician, first in Holland, then in England. In 1780 he retired from medicine to devote himself to literary and philosophical pursuits, returning to the Continent until 1795, then settling once again in England, where he remained, first at Bath, then in London, until his death.
