Lavington was born in London in 1881, and died in Cambridge on 8 July 1927. After schooling he went to work for the Capital and Counties bank in London, but in 1908 went to Emmanuel College, Cambridge to study economics. He was rather older than his contemporaries, such as Hubert henderson and Dennis robertson, and indeed was two years older than his lecturer, John Maynard keynes. He achieved first-class results in both parts of the economics tripos and took his degree in 1911; he then received a research scholarship from Emmanuel, and won the Adam Smith prize in 1912. He then joined the Board of Trade, serving in the Labour Exchanges Department, where he served through the First World War; he was rejected for active service on the grounds of ill health. In 1918 he returned to Emmanuel College and was elected a fellow in 1922. In 1920 he was appointed Girdler's Lecturer in Economics at Cambridge, and held this post until his death.
