George Leslie Rapp

C. W. & George L. Rapp, commonly known as Rapp & Rapp, was an American architectural firm known for the design of movie palaces and other theatres. Active from 1906 to 1965 and based in Chicago, the office designed over 400 theatres, including the Chicago Theatre (1921), Bismarck Hotel and Theatre (1926) and Oriental Theater (1926) in Chicago, the Five Flags Center (1910) in Dubuque, Iowa and the Paramount Theatres in New York City (1926) and Aurora, Illinois (1931).

The named partners were brothers C. Ward Rapp (1860–1926) and George L. Rapp (1878–1941), sons of a builder and natives of Carbondale, Illinois. Their Chicago practice is not to be confused with the Trinidad, Colorado practice of their brothers Isaac H. Rapp (1854–1933) and William M. Rapp (1863–1920) or the notable Cincinnati architects George W. Rapp and Walter L. Rapp, to whom they were not related.
