Pavel Friedman (January 7, 1921 – September 29, 1944) was a Jewish Czechoslovak poet who received posthumous fame for his poem "The Butterfly". Friedman was born in Prague and deported to Theresienstadt concentration camp, in the fortress and garrison city of Terezín (German name Theresienstadt), located in what is now the Czech Republic. He wrote a poem “The Butterfly” on a piece of thin copy paper which was discovered after liberation and later donated to the State Jewish Museum.
Little is known of Friedman's life prior to his incarceration at the Theresienstadt concentration camp, where his arrival was recorded on April 26, 1942. On September 29, 1944 he was deported to Auschwitz, where he died.
