Ferdinand Lassalle was a Prussian-German jurist, philosopher, socialist and political activist who is best remembered as the initiator of the social-democratic movement in Germany. "Lassalle was the first man in Germany, the first in Europe, who succeeded in organising a party of socialist action", according to Élie Halévy. Or, as Rosa Luxemburg put it: "Lassalle managed to wrestle from history in two years of flaming agitation that needed decades to come about".
