Benjamin Philip Watson FRCSEd, FRCOG, FACS (4 January 1880 – 7 August 1976) was a Scottish obstetrician and gynaecologist who was the head of academic departments in three countries.

[3] Three years later he graduated with the degree of Doctor of Medicine (MD) and was awarded a gold medal for his thesis on amniotic fluid and changes in the placenta following foetal death.

During this time he wrote Gynaecological Pathology and Diagnosis in collaboration with Alexander H. Freeland Barbour, one of the earliest English-language textbooks devoted exclusively to this subject.

[5] During World War I he held the rank of captain in the Royal Canadian Army Medical Corps and served in England, Salonika and Egypt.

[3] He radically reorganised the academic department and the teaching of obstetrics and gynaecology but soon found that 'long-established tradition was very hard to fight against'[7] and became frustrated with resistance to his proposals.

[8] His department became known for its academic training, such that nine of his pupils and assistants went on to occupy university chairs in Great Britain, in Canada and the United States.
