Edwin Chadwick

Sir Edwin Chadwick KCB (24 January 1800 – 6 July 1890) was an English social reformer who is noted for his leadership in reforming the Poor Laws in England and instituting major reforms in urban sanitation and public health. A disciple of Utilitarian philosopher Jeremy Bentham, he was most active between 1832 and 1854; after that he held minor positions, and his views were largely ignored. Chadwick pioneered the use of scientific surveys to identify all phases of a complex social problem, and pioneered the use of systematic long-term inspection programmes to make sure the reforms operated as planned.
