Robert Anton Winterberg (27 February 1884 – 22 June 1930) was an Austrian composer, conductor, pianist, and theatre director.

At the age of 15, he produced his first music compositions which included a piano sonata, a string quartet, and several art songs.

American playwright Anne Caldwell adapted it into an English language version for Broadway entitled The Lady in Red which starred Adele Rowland.

This modified version of Winterberg's operetta premiered at Broadway's 44th Street Theatre on 30 August 1916 and enjoyed a New York run of 61 performances before going on tour.

[2] Winterberg's greatest success as an operetta composer among European audiences was Die Dame vom Zirkus (1919) and Günstling der Zarin (1921).
