Renowned Czech composer Zdeněk Šesták has died at the age of 100, according to his biographer Viktor Bezdíček. Šesták was a prominent figure in Czech musical life, creating symphonies, violin concertos, and string quartets. His work also encompassed vocal and choral compositions, including pieces set to Latin liturgical and biblical texts. Beyond composition, Šesták was a musicologist crucial in rediscovering and promoting the legacy of the Cítolib compositional school. His research brought renewed attention to this important, yet previously overlooked, period in Czech musical history. He is remembered for both his original compositions and his dedication to preserving Czech musical heritage. His passing marks the end of an era in Czech classical music.
