Zikmund Michael [Zikmund] Kolešovský (01/05/1817 - 22/07/1868), a Czech composer, born and died in Prague. He was a Czech choirmaster, teacher, composer and critic. He was the son of the distinguished Prague choirmaster František Xaver Kolešovský (b Prague, 1781; d Prague, 12 June 1839), a pupil of J.A. Kozeluch. He studied the violin at the Prague Conservatory, theory, organ and singing at the Prague Organ School, and theory and composition with Tomášek and others. He was a member of the Estates Theatre Orchestra in Prague from 1835 until 1839, when he succeeded his father as choirmaster of St Štěpána; here, and later at St Ignác he continued his father's practice of presenting music by earlier Czech masters, especially F.X. Brixi. In the 1850s he was director of the Žofín Academy, an important Prague music institution with choir and school, but gave up the post to found his own school of singing and theory, where his pupils included Fibich.
