Stanisław Grzesiuk (Polish pronunciation: [staˈɲiswaf ˈɡʐɛɕuk]; 6 May 1918, Małków, Łęczna County - 21 January 1963) was a Polish writer, poet, singer, and comedian. He is notable as one of the few public figures to use and promote the singing style and dialect of pre-war Warsaw after their near extinction in the aftermath of the 1944 Warsaw Uprising.
Stanisław Grzesiuk was born May 6, 1918 in Małków near Chełm. Early in his life his family moved to Warsaw's borough of Czerniaków, a distinct cultural area populated mostly by factory workers and other working poor. After graduating from a local trade school he started work as an electro-technician for various enterprises. After the outbreak of World War II he was arrested by the Germans in 1940 and sent to Germany as a slave worker. However, on April 4 of that year he was sent to Dachau concentration camp for an attempted escape. He was later transferred to Mauthausen-Gusen concentration camp and would spend almost five years there until the camp's liberation by the American army.
Liberated on May 5, 1945, he returned to Poland. Although he survived the Holocaust, his health never recovered and Grzesiuk suffered from serious tuberculosis, which eventually killed him. After the war, Grzesiuk started documenting his pre-war and wartime experiences. In 1958 he debuted with Pięć lat kacetu (Five Years in Concentration Camps), a striking description of his stay in Nazi Germany during the war. The following year he published Boso, ale w ostrogach (Barefoot but with spurs), a description of the pre-war life of Czerniaków, one of the most colorful boroughs of Warsaw. After its publication he became known as the chronicler of life of pre-war Warsaw in numerous songs, including the street ballads for which he became best known. Grzesiuk gained wide popularity as a singer during this period and played a prominent role in various Warsaw traditional-song groups, as a songwriter, singer and banjo player.
