Bradburn was born March 4, 1806, to James and Sarah Bradburn in
Attleboro, a small town in Massachusetts. After his mother died, he was brought up by his half sister Fanny. He first took a trade as a machinist until he decided to pursue further studies at the age on nineteen. He became associated with the
American Anti-Slavery Society in 1839 and he brought forward related radical legislation. He led a movement which repealed a marriage law. After this change, "People in Massachusetts, wishing to marry, are under no necessity of comparing complexions" After they arrived many took the opportunity to tour England. Bradburn was able to visit various places including
Blenheim Palace,
Eaton Hall,
Stratford on Avon,
Oxford University and
Warwick Castle.
William Lloyd Garrison, who was not there until the 17th,
Henry Grew spoke in favour of the men's rights to exclude women despite his daughter being one of the excluded delegates. The American women had to join the other female observers like
Lady Byron and were not allowed to participate in the convention. Not only was the equality of the sexes debated, but Bradburn said that "introducing any such words as 'Christian,' 'Religious,' and the like, by which persons of any religion whatever, or of no religion whatever, should be excluded from the Anti-Slavery platform. The portrait of Bradburn which is shown at the top of this article and in
Haydon's picture of the 1840 World Anti-Slavery convention was completed in a small room at the Freemasons hall where the convention was held. Bradburn commented that he felt that he had been given "too much severity or sharpness," but Haydon assured him that he looked "revolutionary" when giving his speeches. Bradburn made time after a visit to France to complete a third sitting on August 3, 1840. Bradburn then visited
Newcastle, Scotland and Ireland, visiting people he had met at the convention including the Irish Nationalist leader
Daniel O'Connell and Lady Byron, the mathematician (and the poet's estranged wife). ==100 conventions==
