On returning to Cambridge, Gilmour succeeded Humphrey Gilbert-Carter as director in 1951, he was an important force in the development of the Eastern Garden, once the Cory Fund monies became available, and the Cory Laboratory and glasshouses were constructed in 1957. His scientific contributions were largely in the field of systematics and horticulture, playing an important role in the Systematics Association.
