Josef Ivanovici (alternatively, Iosif Ivanovici, Ion Ivanovici)
born 1845 in Timişoara, died in September 28, 1902
was a Romanian composer. He wrote over 350 dance pieces and marches, but today his only work known to the public is "The Waves of the Danube" (Romanian: Valurile Dunării) — listen here — a waltz, which was performed at the 1889 Paris Exposition and took the audience by storm.
A World War II film titled Valurile Dunării directed by Liviu Ciulei was produced in Romania in 1959, and the waltz by Ion Ivanovici was used in the film.
