John Addenbrooke (philanthropist)

John Addenbrooke (1680 – 7 June 1719) was an English medical doctor and philanthropist, who left more than £4,500 (equivalent to about £839,301 in 2023) in his will for the founding of a hospital for the poor. Addenbrooke's Hospital, which has expanded significantly since its beginnings, is now a major teaching hospital in Cambridge, England.

Addenbrooke studied at Catharine Hall, now St Catharine's College, a part of the University of Cambridge. He was later a fellow and bursar there, and bequeathed a collection of rare medical books to the college library.
