Ferdinand Lassalle

Ferdinand Lassalle was a Prussian-German jurist, philosopher, socialist and political activist 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", or, as Rosa Luxemburg put it: "Lassalle managed to wrestle from history in two years of flaming agitation what needed many decades to come about." As agitator he coined the terms night-watchman state and iron law of wages.
