About Stanisław Jerzy Lec
Stanisław Jerzy Lec (Polish pronunciation: [staˈɲiswaf ˈjɛʐɨ lɛts]; 6 March 1909 – 7 May 1966), born Baron Stanisław Jerzy de Tusch-Letz, was a Polish aphorist and poet. Often mentioned among the greatest writers of post-war Poland, he was one of the most influential aphorists of the 20th century, known for lyric poetry and ironic philosophical-moral aphorisms, often with a political subtext. In 1935 he co-founded the satirical magazine Szpilki (Pins). A "literary cabaret" he founded in Lwów in collaboration with Leon Pasternak in 1936 was closed by the authorities after several performances.
