Otto Stransky (* May 15, 1889 in Brno, Austria-Hungary; † November 23, 1932 in Berlin) was an Austrian operetta, revue and film composer.
After attending school, Stransky studied at the Leipzig Conservatory with Arthur Nikisch and Max Reger, and from 1910 was répétiteur and Kapellmeister at the Leipzig Theater. Under Max Reinhardt's direction he conducted performances of the ''Mirakel''in Vienna. He worked at the ''Raimundtheater'' in Vienna and at the ''Theater an der Wien''. In 1915, Stransky became musical director of the Viennese cabaret ''Simplizissimus''. After the First World War and the completion of his military service, Stransky was engaged as a house composer and piano accompanist at various Berlin cabarets from 1921. From 1926, he worked for Kurt Robitschek's ''Kabarett der Komiker'' (KaDeKo).
Stransky was successful as an operetta and revue composer as well as a film composer. In 1929, he wrote music for the singer's short film ''In Jena sind alle Mädels so blond'' with the tenor Franz Baumann (1890-1965), and later another 20 popular hits for sound films. The best known of these were the melodies from the sound film ''Die oder keine'' (1932), which was heavily attacked by the National Socialists because of the mockery of Wagner's works it allegedly contained. The song ''Wenn man sein Herz verliert - Weiss keiner, wohin das führt'', whose lyrics were written by Johannes Brandt (1884-1955), was taken from the film. Brandt was also responsible for the screenplay and Stransky for the musical direction. A year earlier he had written the music for Alfred Zeisler's sound film ''Sein Scheidungsgrund'' (Germany-1931). The lyrics were written by Ruth Feiner, and in the film the ''Dajos'' orchestra played Béla Stransky's melodies.
Otto Stransky also wrote, often together with Fritz Rotter, the lyrics to revues, for example in 1927 for Rudolph Nelson's revue ''Die Lichter von Berlin'', as well as to other daytime hits. He wrote a number of songs for the Berlin chanson singer Claire Waldoff.
He also used the pseudonyms Wenzel Müller and Enrico Sarroni.
Stransky died in a car accident in Berlin in 1932.
