Andrew Duncan (physician, born 1773)

Andrew Duncan, the younger (10 August 1773 – 13 May 1832) was a British physician and professor at the University of Edinburgh.

Duncan studied in London in 1794–5 at the Windmill Street School, under Matthew Baillie, William Cumberland Cruikshank, and James Wilson.

In 1819 he resigned his professorship of medical jurisprudence on being appointed joint professor with his father of the institutes of medicine.

[6] Duncan in 1803 published the Edinburgh New Dispensatory, an improved version of William Lewis's work.

From 1805, he was for many years chief editor of the Edinburgh Medical and Surgical Journal, which gained a leading position in the field.

Perhaps his most distinctive discovery was the isolation of the principle cinchonin from cinchona, as related in Nicholson's Journal, 2nd ser.
