Boyd Collection

Boyd Collection is an archival collection of human embryonic material held at the University of Cambridge. The specimens were collected in the 1950s and 1960s by Professor JD Boyd, Professor of Anatomy at the University. Professor Boyd was a leading embryologist who wrote the classic monographs 'Human Embryology' (Hamilton, Boyd and Mossman) and 'The Human Placenta' (Boyd and Hamilton). Because of his research interests local pathologists sent Professor Boyd specimens for review. The collection is comprised solely of histological sections, and no tissue blocks remain.
