Josef Kainar (29 June 1917 in Přerov, Austria-Hungary – 16 November 1971 in Dobříš, Czechoslovakia) was a Czech poet, lyrics writer, dramatic author and translator, but also a musician, illustrator, artist and journalist.
His work being highly lyrical was able to connect with music; it was colloquial, sometimes even vulgar in its opposing conservatism.
In the early 40s he wrote lyrics mainly to American swing classics (George Gershwin, R. Rodgers, D. Ellington, H. Carmichael et al.).
During the occupation the Nazis condemned it as "Jewish-Bolshevik filth", which was nevertheless played among the youth, particularly on tramping meetings.
the songs Černá kára, Starý mrtvý vrabec, Blues železničního mostu.
