Lord Brougham, the most prominent champion of anti-apprenticeship, acknowledged Sturge's central role in rousing British anti-slavery opinion in a speech to the House of Lords. In 1839, Sturge and others from the anti-apprenticeship campaign came together to found the British and Foreign Anti-Slavery Society, which survives until today as Anti-Slavery International. The new organization turned its attention to emancipating slaves outside Great Britain's borders. In 1841 Sturge traveled in the United States with the poet John Greenleaf Whittier to examine the slavery question there.
-- Folded letter (June 10th, 1841) addressed at front from Sturge and signed by Joseph Sturge to Governor Pennington, State of New Jersey -- Inside reads--- To The Governor of New Jersey Respected Friends I herewith forward thee a copy of a publication issued recently in England relative to American Slavery. The kind and candid tone of thy letter to Thomas Clarkson , so honorably contrasting with those of some of the Chief Magistrates of the other States , induces me to hope that thou will on all suitable occasions exert thy personal influence and the prerogatives of thy station to promote the great cause of Universal Liberty. Thy friend Joseph Sturge, Philadelphia June 10th 1841.
