Ferdinand Lassalle

Ferdinand Lassalle (11 April 1825 – 31 August 1864) was a Prussian-German jurist, philosopher, socialist and politician 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".

As an agitator, he coined the terms night-watchman state and iron law of wages. Provided by Wikipedia
