Jaroslav Ježek (IPA: [ˈjaroslaf ˈjɛʒɛk]) (September 25, 1906 - January 1, 1942) was a Czech composer. He was born in Prague, and died in New York City. The almost blind Ježek studied composition under Josef Suk and Alois Hába at the Prague Conservatory. When Ježek met playwrights/comedians Jan Werich and Jiří Voskovec (aka George Voskovec), leaders of the Osvobozené Divadlo (Liberated Theatre) in Prague, he took up the post as main composer and conductor.
