its Guy Medal in Gold in 1935 and he served as its president 1938–40. Personal life According to Allen and George, "In personality Bowley was somewhat shy and retiring. He did not readily make friends and his close friendship with Edwin Cannan over many years was an almost unique experience." They recall an anecdote about an occasion when Bowley and Cannan were cycling with Edgeworth. When Edgeworth wanted to discuss a mathematical question Cannan said, "Bowley, let us go a little faster, Edgeworth cannot talk mathematics at more than eight miles an hour." Bowley married Julia Hilliam in 1904 and the couple had three daughters. His daughter, Marian Bowley, also had an academic career in economics. Bowley's law Bowley formulated Bowley's law, which says that the proportion of GNP from labour is constant. Main publications of A. L.
