Giangiacomo Feltrinelli (Italian: [d?an'd?a?komo feltri'n?lli]; 19 June 1926 – 14 March 1972) was an influential Italian publisher and businessman active following the Second World War.
He founded a vast library of documents mainly in the history of international labor and socialist movements.
He became a militant and clandestine left-wing activist preceding the Years of Lead.
Feltrinelli is perhaps most famous for his decision to translate and publish Boris Pasternak's novel Doctor Zhivago in the West after the manuscript was smuggled out of the Soviet Union, in the late 1950s.
