Heine (Heinrich), German poet and littérateur, b. of Jewish parents at Dusseldorf, 31 Dec. 1797. He studied law at Bonn, Berlin, and Göttingen; became acquainted with the philosophy of Spinoza and Hegel; graduated LL.D., and in June 1825 renounced Judaism and was baptised. The change was only formal. He satirised all forms of religious faith. His fine Pictures of Travel was received with favor and translated by himself into French. His other principal works are the Book of Songs, History of Recent Literature in Germany, The Romantic School, The Women of Shakespeare, Atta Troll and other poems. In 1835 he married a French lady, having settled in Paris, where "the Voltaire of Germany" became more French than German. About 1848 he became paralysed and lost his eyesight, but he still employed himself in literary composition with the aid of an amanuensis. After an illness of eight years, mostly passed in extreme suffering on his "mattress grave," he died 17 Feb. 1856. Heine was the greatest and most influential German writer since Goethe. He called himself a Soldier of Freedom, and his far-flashing sword played havoc with the forces of reaction. Heinzen (Karl Peter) German-American poet, orator and politician, b. near Dusseldorf, 22 Feb. 1809. He studied medicine at Bonn, and travelled to Batavia, an account of which he published (Cologne 1842). A staunch democrat, in 1845 he published at Darmstadt a work on the Prussian Bureaucracy, for which he was prosecuted and had to seek shelter in Switzerland. At Zurich he edited the German Tribune and the Democrat. At the beginning of '48 he visited New York but returned to participate in the attempted German Revolution. Again "the regicide" had to fly and in August '50 returned to New York. He wrote on many papers and established the Pioneer (now Freidenker), first in Louisville, then in Cincinnati, then in New York, and from '59 in Boston. He wrote many works, including Letters on Atheism, which appeared in The Reasoner 1856, Poems, German Revolution, The Heroes of German Communism, The Rights of Women, Mankind the Criminal, Six Letters to a Pious Man (Boston 1869), Lessons of a Century, and What is Humanity?
