PRAGUE—Lubomir Doruzka, a renowned Czech music critic who led his readers through the world of jazz in the turbulent 20th century, has died. He was 89.

Doruzka's son Petr confirmed his Monday's death to Czech public radio, where Doruzka had a regular jazz show.

Born March 18, 1924, Doruzka first wrote about jazz for an underground magazine during World War II when Czechoslovakia was occupied by Nazi troops and jazz coming from the American enemy was banned.

After 1948 Communist takeover, Doruzka gave Czechs a chance to read the literature of the Jazz Age with his translations of F. Scott Fitzgerald.

He published a number of jazz and pop music books and helped create Prague's International Jazz Festival and International Jazz Federation.
