Barbara Bradby was the daughter of a headmaster of Haileybury College. She attended secondary school at St. Andrews and St. Leonard's, and then graduated with honors with a degree in the classics from Oxford University. In 1901, she married fellow author and historian John Lawrence Hammond (1872-1949), with whom she collaborated in writing many works, including the series The Village Labourer (1911), The Town Labourer (1917) and The Skilled Labourer (1919), which etched starkly the lives of poor workers during the Industrial Revolution. In 1933, Oxford University gave recognition to the parity of their contribution by conferring on each of them an honorary D.Litt. degree. Barbara Bradby Hammond also wrote The Rise of Modern Industry (1925) as well as a several biographies. See an account of their lives and work in Liberals and Social Democrats (1978), by Peter Clarke.
