Career
In the early 1920s, he formed the Kagan"s Jazz Band in Warsaw, performing in operettas, cabarets, and hotels. Since 1922 Kagan was a feature artist at the Kabaret Mirage and at the Teatr Nowości. In 1926 he signed a contract with the luxury Hotel Bristol in Warsaw.
His band performed world-renowned standards as well as his own compositions widely popular across the country.
He died in Warsaw during the Holocaust in occupied Poland. Kagan was one of four sons of Morduch (Mordechai) and Sara née Kantor.
He was born in Nowogródek (now Navahrudak in Belarus). Jakub followed in his brother"s footsteps.
He began composing at that particular time.
His first widely popular tango was "Złota pantera" (The Gold Panther) to words by Andrzej Włast (1895–1942), premiered in 1929 in ŻegiestóWest The song opened all the doors for his subsequent Warsaw career, followed by international tours and concerts in Germany, Austria, and Hungary. His greatest hits were performed by such headliners as Hanka Ordonówna, Adam Aston, and Stanisław Grzesiuk.
After the invasion of Poland by Nazi Germany he was deported to the Warsaw Ghetto where he played piano at the Splendid Café and the Melody Palace Theatre to survive.
He was killed in 1942 possibly during the murderous Grossaktion Warsaw. Only the youngest of the Kagan brothers, Alexander (born in 1906), survived the Holocaust as a soldier of the Polish Army in France (1939-1940), interned in Switzerland.
