By the time Streeter retired and the new director,
George Corner, had arrived, this new
direction was firmly in place. Corner, a former Johns Hopkins researcher who
had discovered the ovarian hormone
progesterone, came to the department from the University of Rochester. Under
his leadership, many advances in the understanding of human reproductive
physiology were made. Still, the work in human
embryology continued.
It wasn't until Corner's successor was in place that the human embryology work was terminated. James Ebert, an expert on tissue transplantation and heart development, arrived as director in 1956. Ebert was well aware of the new revolutionary discoveries that had begun to redefine biology. He began to transform the work of the department accordingly. Under his leadership, new investigations initiated the molecular and genetic study of development. In 1973, the Human Embryo Collection was sent to the University of California at Davis, where the Carnegie Laboratories of Embryology, under the directorship of Ronan O'Rahilly, opened in 1976. In 1991, following O'Rahilly's retirement, the collection was donated to the National Museum of Health and Medicine. |
