Čestmír Gregor (14 May 1926 – 2 March 2011) was a Czech composer, theorist and publicist.
He then continued studies in studio tracks with Kvapil at the Janáček Academy of Music and Performing Arts, which he eventually completed in 1970.
[2] He served as secretary of the creative branch of the Union of Czechoslovak Composers.
In 1968 the arrival of Warsaw Pact troops disrupted his work at the radio station, and in 1972 Gregor was banned from publishing.
As a composer, Gregor was initially heavily influenced by 20th century classical music, especially that of Igor Stravinsky, and by jazz.
