"William Ewart Gladstone (1809 - 1898)

Four-time prime minister of Great Britain, Gladstone remained a vigorous campaigner until his death.
Having been persuaded against a career in the Church, Gladstone was elected to Parliament in 1832, as a Tory. He made his mark from the start and held minor office in Peel's government of 1834-35. In July 1839 he married Catherine. The two maintained a 'rescue' home for prostitutes and Gladstone would, famously, trawl London streets at night, trying to persuade prostitutes to start a new life.
Although he was slowly moving towards liberalism, in 1843 he entered Peel's Conservative cabinet. However, in 1852 he joined Aberdeen's Whig government as Chancellor of the Exchequer, a position he would ultimately hold three times. His efforts to extend the franchise failed and ended the government in 1866. Two years later, the Liberals were back, with Gladstone in charge. Queen Victoria, who disliked him personally, was forced to ask him to become prime minister.
