In 1933 Hodgkin was awarded a research fellowship by Somerville College, and in 1934, she moved back to Oxford. The College appointed her its first fellow and tutor in chemistry in 1936, a post which she held until 1977. In the 1940s, one of her students was Margaret Roberts (later Margaret Thatcher) who, while Prime Minister, hung a portrait of Hodgkin in her office at Downing Street out of respect for her former teacher. Hodgkin was, however a life-long Labour Party supporter.
