Sir Thomas Millington FRS (1628 in Newbury – 5 January 1703/04 in Gosfield), the son of Thomas Millington, was an English physician. Greatly respected in his day, he was eulogised by Samuel Garth under the name of Machaon in his poem 'The Dispensary' while Thomas Sydenham held him in high regard. Millington had ventured in a conversation with Nehemiah Grew that the stamen ("attire") serves as the male organ for the production of the seed. Grew at once "replied that he was of the same opinion, gave some reasons for thinking so, and answered some objections which might be made to it."
