He became the first principal of the University College of Swansea in 1920 and he played a crucial role in setting the new institution on a firm foundation. He was a firm and strong leader, a forceful advocate and a gifted administrator. It has been claimed that it was due to him that the new college was not allowed to harbour an inferiority complex in its relations with its older sister colleges in the University. In 1926 he was appointed Chief Officer of the University of London, a title changed at his appointment to Principal, and he became Vice-chancellor of the University of Reading 1929-46, where he did much to guide the development of the young university. His skills as a negotiator ensured that he was a leading figure in British university administration.
