an English physician. Addington was educated at Trinity College, where he took the degree of M.A. and M.D. He was a fellow of the College of Physicians, and went into practice in London, but was compelled by bad health to move to the country. His career gained considerable public attention when he appeared as an expert for the prosecution of Mary Blandy for the poisoning of her father in 1752. He then retired to Reading, where he derived a large income from his profession, until his death. He devoted his attention particularly to the treatment of insanity, and was one of the physicians called in to see George III when he first showed symptoms of mental aberration.
