Leó Frankel

Leo Fränkel 25 February 1844, Altofen-Neustift, Austro-Hungarian Empire – 29 March 1896, Paris) was a socialist revolutionary, labour leader of Jewish descent.

Fränkel was born in 1844, in Újlak [hu] (now part of Budapest, Hungary but at the time known in German, the ruling language of the Austrian [after 1867: Austro-Hungarian] Empire, as Altofen-Neustift).

Trained as a goldsmith, Fränkel first went to work in Germany in 1861, where he became involved with Ferdinand Lassalle's Allgemeiner Deutscher Arbeiterverein sometime between 1865 and 1866.

Fränkel was elected as a member of the Paris Commune, which he served as the delegate responsible for labor, industry, and trade, regulating hours of work, and the organization of workers' cooperatives.

He also supported the international congress of socialist parties (French, German, Belgian and Swiss) that met in Chur, Switzerland, which would lead to the foundation of the Second Internationale but was tried and sent to prison for a year and a half for the infringement of the prevailing press law in 1881.
