Smith was born on 17 April 1864 in Bristol, and died on 19 September 1945 in Wiltshire. He was the son of Samuel Wyatt Smith and his wife Louisa. After attending Bristol Grammar School, Smith went up to Corpus Christi College, Oxford, where he studied mathematics. He took firsts both in the mathematical moderations and in his final exams. He also won the Cobden Prize in 1885, and his essay, Economic Aspects of State Socialism, was published in 1887. Smith married Edith Weekley in 1901, and they had six children. He retired from the civil service in 1927, but this was far from the end of his public life. He was awarded the CB in 1903, was knighted KCB in 1908 and received the GCB in 1919. In 1934, he was made an honorary fellow of Corpus Christi College.
