Who was Ferdinand Lassalle?

Socialist leader Ferdinand Lassalle (1825-1864) was born in Breslau, Germany. He was roughly a contemporary of Karl Marx (with whom he corresponded for several years), but while Marx advocated a revolution of the proletariat, Lassalle championed an evolutionary approach. He was a founder of the German labor movement. Lassalle held that the German working class had to organize itself into a national association whose immediate goal would be direct, universal suffrage. He was in touch with leading intellectuals and writers of his time, including Heinrich Heine, and with several leaders of the abortive 1848 revolutionary movement. In his books he envisioned a better world under a fair-minded proletarian government. The Nazis burned Ferdinand Lassalle's works, some 70 years after his death, because of their socialist doctrine.
