Теперь о Леопольде Тырманде.
Leopold Tyrmand (May 16, 1920 in Warsaw, Poland – March 19, 1985) was a popular Polish-Jewish novelist, writer and editor.
Tyrmand emigrated from Poland to the United States in 1966.
Leopold Tyrmand was born in an assimilated Jewish family.
During the war Tyrmand was a resistance fighter in Poland.
In spring 1941 he was arrested by the NKVD secret police in Wilno and sentenced to 8 years in prison.
He got out from a bombed-out transport after the Nazi German attack on the Soviet positions in Operation Barbarossa.
To escape the Holocaust, he traveled on false papers to Germany.
He worked as a waiter while in Germany; an experience he wrote about in his semi-autobiographical novel "Filip".
He tried to escape to neutral Sweden and was caught and imprisoned in a Nazi concentration camp Grini in Norway.
Before he returned to a devastated Poland, he worked with the Norwegian Red Cross
In 1954, he wrote a diary, which he later edited and released in 1980 as "Dziennik 1954"; it has been translated into English and was published in 2014 as Diary 1954.
The book, which gives a unique description of the daily life in Stalinist Poland, is now considered to be one of his greatest achievements.

In 1950, during the years of Stalinism in Poland, Tyrmand was removed from the editorial board of popular Przekrój magazine for his report about a boxing tournament, in which he criticized the Russian judges for their pro-Soviet bias
