Julius Ernst Wilhelm Fučík (18 July 1872, Prague- 25 September 1916, Berlin) was a Bohemian (present-day Czech) bandmaster and composer. Fučík studied violin, bassoon, and composition (with Antonín Dvořák) and was a bassoonist in a number of opera orchestras. The composer became one of the most prolific European composers of his time, producing more than 400 works including operettas, chamber music, masses, marches and a symphonic suite.
In a short brilliant career as bandmaster to the 86th Hungarian Infantry Regiment, Fučik developed his own wide-ranging style of writing marches. Of his more than 100 marches, Entry of the Gladiators March (also known as Thunder and Blazes), Children of the Regiment and Florentiner are probably the best known. Today his marches are still played as patriotic music in the Czech Republic. However his world-wide reputation rests on one work, his opus 68 march the Entry of the Gladiators (Vjezd gladiátorů), which is universally recognized as the theme tune of clowns in a circus.
