John George Graves was a successful English entrepreneur and public benefactor. He became Sheffield's Lord Mayor and an Alderman in 1926 and he was given Freedom of the City in 1929. He was born in Lincolnshire in 1866 and died in 1945, after having settled in Sheffield. Graves moved to Sheffield to become an apprentice watchmaker. He set up one of Britain's first mail order businesses, selling first watches and then a wide range of goods. The company employed, at its peak, 3,000 people in Sheffield and had an annual turnover of �1m. The company was absorbed by Great Universal Stores after Graves' death. A keen art collector, Graves donated nearly �60,000 towards the development of art galleries in Sheffield, including Sheffield Central Library, the Graves Art Gallery and the Mappin Art Gallery. He also contributed hundreds of pictures from his private collection. Between 1902 and his death in 1945, Graves lived at Riverdale House in the Ranmoor area of Sheffield. Graves donated over �1 million to Sheffield, including the establishment of Sheffield University's Student Union. Part of the Union building is known as the "Graves Building".
