Lees-Smith was from an army family. His father was a major in the
Royal Artillery and he was born in
British India. He was educated at
Aldenham School, as a cadet at the
Royal Military Academy, Woolwich, and
Queen's College, Oxford. Rejecting a military career, he chose academia and was appointed as a lecturer in Public Administration at the
London School of Economics in 1906, where he remained throughout his political career. He was also Chairman of the Executive Committee of
Ruskin College, Oxford, from 1907 to 1909. He resigned on appointment as Professor of Public Administration at the
University of Bristol. In 1909, he went on an extended tour of India to lecture at
Bombay on economics and advise on economics teaching. As a result of his experiences he wrote
Studies in Indian Economics. He joined a
territorial regiment in 1915, and was wounded as a
stretcher bearer on the Western Front and invalided out of the armed forces in 1917. He married Joyce Holman in 1915, and they had two children. In 1938, he distributed 40 British passports to German Jews in Frankfurt, thus aiding their escape.
