Which of these men died in 1833, three days after the Slavery Abolition Act was passed by the House of Commons?

William Wilberforce (24 August 1759 – 29 July 1833) was an English politician, philanthropist, and a leader of the movement to eradicate the slave trade. A native of Kingston upon Hull, Yorkshire, he began his political career in 1780, eventually becoming an independent Member of Parliament (MP) for Yorkshire (1784–1812). In 1785, he became an Evangelical Christian, which resulted in major changes to his lifestyle and a lifelong concern for reform.

In later years, Wilberforce supported the campaign for the complete abolition of slavery, and continued his involvement after 1826, when he resigned from Parliament because of his failing health. That campaign led to the Slavery Abolition Act 1833, which abolished slavery in most of the British Empire; Wilberforce died just three days after hearing that the passage of the Act through Parliament was assured. He was buried in Westminster Abbey, close to his friend William Pitt.
