Born in Vienna, Leopoldi was the eldest son of the musician Leopold Kohn (the official change of surname to Leopoldi took place in 1911).[1] He taught him and his brother Hermann how to play the piano. He also tried to get engagements for the two; already at the age of six Ferdinand appeared as a pianist. Like his brother, he spent the First World War with the K.u.k. Infanterieregiment "Hoch- und Deutschmeister" Nr. 4 [de]. Afterwards, both often had common appearances in the Ronacher and other amusement pubs and bars. In this time Leopoldis first hits came into being. In 1918 he was one of the co-founders of the International Artist Organization.
As solo pianist in Viennese cafés/bars he was advertised as Ferdinand Leopoldi, his brother Hermann as Leopoldi.[2]
In 1922, together with the lecturer Fritz Wiesenthal[3] (died 31 December 1936 in a sanatorium located in Mauer, Vienna at age 53/56),[4] Hermann und Ferdinand Leopoldi opened the cabaret "Leopoldi-Wiesenthal", short "L.W.", in the Rothgasse 5[5] in the first district of Vienna. The restaurant soon became known far beyond the regional borders. In addition to Leopoldi-Wiesenthal, more or less regularly appeared Charlotte Waldow,[6][better source needed] Franzi Ressel,[7]Armin Berg [de], Hans Moser, Szöke Szakall, Max Hansen, Fritz Grünbaum, Karl Valentin or Raoul Aslan and Otto Tressler. In 1925, however, they had to close the restaurant for financial reasons, none of the managers had ever learnt how to do business. They then made guest appearances in Berlin and Switzerland and undertook tours.
Towards the end of the 1920s, the Leopoldi brothers gradually went their separate ways. Hermann had more and more solo appearances, Ferdinand took part in the 1926 movie Die Pratermizzi and was mainly active as bar pianist before he had numerous appearances with Robert Rakowianu[8] (1886-1938) and Grete von Király on the radio in the 1930s.
After the Anschluss of Austria, his brother Hermann was deported to the Dachau Concentration Camp in 1938 and was able to emigrate to the US in 1939. Leopoldi, who was married to an Aryan, stayed in Vienna and lived secretly during the Austria under National Socialism period in an apartment in the Viennese Bellariastraße [de]. However, he was discovered there in 1943 and taken to an interrogation by the Gestapo, the consequences of which killed him in the Rothschild Hospital.[9]
