Chapman was born at Wells, Norfolk on 20 April 1871, the son of a businessman, and died at Ware, Hertfordshire on 29 August 1951. His family moved to Manchester when Chapman was Young, and he was educated Manchester Grammar School and Owens College. He then attended University of London, taking a degree in history in 1891 and subsequently taught at a school in London; he also contemplating entering the Church of England and training as a priest. He entered Trinity College, Cambridge in 1894, initially to study philosophy, but by chance enrolled in a class on economics taught by Alfred marshall. This convinced him to take up the study of economics, and Marshall became a lifelong mentor and friend. A brilliant student, Chapman won both the Cobden and Smith prizes and took first-class honours, graduating with a BA in economics in 1898.
