Sir George Barham (22 November 1836 – 16 November 1913) was an English businessman and founder of the Express County Milk Company, later to become Express Dairies. He is sometimes described as the father of the British dairying industry.^[1]

Barham was born in November 1836 at the Strand, London, younger surviving son of Robert Barham (1807-1888), who owned a retail dairy and had been a licensed victualler, and Altezeera Henrietta (died 1886), daughter of George Davey, of Bletchley, Buckinghamshire. Robert Barham was a younger son of a long-established family of Sussex yeoman farmers and ironmasters, from which also came John Barham, a High Sheriff of Sussex, and the lawyer and politician Nicholas Barham.^[2][3]
