Rehabilitation
After the deaths of Soviet leader Joseph Stalin (1953) and Polish leader Bolesław Bierut (1956), Leski was freed and soon rehabilitated. Still, he could not find a job, as Poland's communist authorities continued to view former Home Army soldiers with suspicion. He had to give up work in the shipbuilding industry and worked as a clerk at the PWT publishing house. Eventually he became a member of the Polish Academy of Sciences. Awarded a doctorate, for political reasons he could not receive the rank of professor for his work on computer analysis of natural language codes. Nevertheless, he continued his scientific work, publishing seven books and over 150 other publications. He also patented inventions.
Largely unknown to the public, in 1989—after Solidarity's victory and the fall of the communist regime—he published his memoirs, which became a best-seller. He received the Polish PEN Club Prize and the Polish Writers' Society in Exile Award.
He died on 27 May 2000 and was interred with military honors at Warsaw's Powązki Cemetery.
