Franz Jakubowski (10 June 1912, Posen, Province of Posen, Prussia, Germany, now Poznan, Poland – 1970, U.S.) was a Western Marxist theorist.
Born in Prussia, he grew up in what was then the Free City of Danzig.
His father was a doctor.
From 1930 to 1933 he studied law in Heidelberg, Berlin, Munich and Breslau, before completing his studies in political science at Basel University.
After student activism and the agitational role he would briefly play in Danzig, Jakubowski abandoned Europe, and settled in the USA, changing his name to Frank Fisher and marrying Margaret Citron with whom he had two children Thomas and Robert Fisher.
In the 1970's he moved back to Europe and married Elisabeth Spanjer.
There he would play a part in establishing the Alexander Herzen Foundation, a publisher of samizdat soviet literature.
