On his return to England he joined in 1930 the Sub-Department of Oriental Prints and Drawings at the British Museum, under Laurence Binyon, in 1940 becoming the Department's deputy keeper, and in 1946, its keeper. Under his tenure he managed employment intake, collections and acquisitions, and curated special exhibitions using the Department's own collections, and those from public and private sources.[2][3]
The archeologistRoman Ghirshman invited Gray to Iran in 1951, to study Ville Royale excavations at Susa. Further visits to Iran included Iranian Institute's and British Council lectures at Isfahan, Tabriz, and Mashhad, and for Shiraz he urged, as a member of the Iranian Institute governing body, investigations of the dye trade between the Persian Gulf and China.[3]
He became the temporary Director of the British Museum in 1968, and retired in 1969. During retirement his focus turned to the relationship between Chinese ceramics and Persian painting. He became Vice-President of the British Institute of Persian Studies in 1969, chaired the Sixth International Congress of Iranian Art and Archaeology at Oxford in 1972, and became President of the Societas Iranologica Europara in 1983.[3] As an art historian Gray wrote exhibition guides and books on Orientalism and Islamic Art.
A curatorial position in the Department of Asia at the British Museum is named after Gray.[4]
