Karel Kalaš

Karel Kalaš (9 October 1910 – 3 May 2001) was a Czech operatic bass and film and television actor. He first rose to prominence at the Slovak National Theatre, where he was a member from 1934 through 1939. He left there to join the roster of principal singers at the National Theatre in Prague, where he worked until his retirement from the opera stage in 1972. He appeared in a handful of films and occasionally on Czech television during his career, notably winning acclaim for his portrayal of a retired opera singer in the 1978 film Kulový blesk.

Kalaš's voice is preserved on a large number of recordings made on the Ultraphon, Esta, Bruno, Multisonic, and Urania labels. He also appeared on a number of complete opera recordings with the Prague National Theatre on the Supraphon label.
