Chartist leader and poet, born at Berlin, of English parentage, educated at Göttingen; came to England in 1838, and six years later was called to the bar; in 1845 he threw himself into the Chartist movement, and devoted the rest of his life to the amelioration and elevation of the working-classes, suffering two years' (1848-1850) solitary imprisonment for a speech made at Kensington; he wrote, besides pamphlets and papers in the Chartist cause, several poems; "The Revolt of Hindostan" was written in prison, with his own blood, he said, on the fly-leaves of a prayer-book; he never succeeded in getting into Parliament (1819-1869).
