and one of the principal founders of German social democracy. A flamboyant Hegelian, Lassalle (born Lasal; he Frenchified his name since France was the home of revolution) lived a colourful and hectic life that was ended by a duel. He agitated for the cause of the workers and the ending of capitalism. His works include Die Philosophie Herakleitos des Dunklen von Ephesos (1858), and the System der erworbenen Rechte (1861).
