Sir Thomas Fowell Buxton, 1st Baronet (1 April 1786 – 19 February 1845) was an English Member of Parliament, brewer, abolitionist and social reformer.
Buxton was born at Castle Hedingham, Essex. His father was also named Thomas Fowell Buxton. His mother's maiden name was Anna Hanbury. Through the influence of his mother, who was a Quaker, Buxton became associated with the Gurney family of Earlham Hall, Norwich. He was especially close to Joseph John Gurney, his sister the prison reformer Elizabeth Fry, and their sister Hannah, whom he married in May 1807. He lived at Northrepps Hall in Norfolk.
In 1808, Buxton's Hanbury family connections led to an appointment to work at the brewery of Truman, Hanbury & Company, in Brick Lane, Spitalfields, London. In 1811 he was made a partner in the business, renamed Truman, Hanbury, Buxton & Co. He later became sole owner.
Although he was a member of the Church of England, Buxton attended meetings of the Religious Society of Friends (Quakers) with some of the Gurneys. In this way he became involved in the social reform movement, in which Friends were prominent. He helped raise money for the weavers of London, who were being forced into poverty by the factory system. He provided financial support for Elizabeth Fry's prison reform work and joined her Association for the Improvement of the Female Prisoners in Newgate.
