Osborne O. Heard

Osborne O. Heard (1891–1983) produced model reconstructions for the Carnegie Institute. He spent 42 years at the department and made over 700 wax-based embryo reconstructions models. The models were mainly made by the lost-wax casting process. His models were also more detailed than the earlier Ziegler embryo models (1880's).
