After studies at the Condorcet high school, he studied medicine in Paris, and graduated in 1947. He joined the Bolshevik Leninist Group, the Trotskyist organization, in September 1936. By 1944 the Trotskyist was a member of the Internationalist Communist Party , (PCI), the French section of the Fourth International. Bleibtreu led workplace cells of the PCI around Puteaux-Suresnes-Nanterre under the pen-name Pierre Favre. In November 1944, he became an editor of the party’s newspaper, The Truth.

Lambert supported the MTLD of Messali Hadj while others, along with Bleibtreu, supported CRUA (the fore-runner of the FLN). Lambert was able to win a majority in 1955, expelling Bleibtreu and its comrades. The expelled group took over the Bolshevik-Leninist group and published the Trotskyism review. The GBL later joined the New Left , Within qui Bleibtreu created the Revolutionary Socialist Tendency, a founding member of the UGS and the PSU.
