The Rambusch Decorating Company was founded in 1898 in New York, New York by Frode Rambusch, a Danish immigrant.
In the 1920s, Rambusch was the decorator for many elaborate movie palaces, including the Roxy Theatre in New York City, which seated 6,214 and opened in March 1927. That project was supervised by Harold Rambusch, working with architect Walter W. Ahlschlager. It also designed the interior of the Mark Hellinger Theatre, which was built in 1930 as a movie house but was later converted to a Broadway theatre. The firm helped decorate the main public rooms at the Waldorf-Astoria hotel when it was built in the early 1930s. It also helped make some of the stained glass windows at St. Bartholomew's Church on Park Avenue. The firm also employed later generations of Rambusches, including Viggo F. E. Rambusch.
During World War II, the firm helped camouflage American airfields from enemy planes. Sketches of orchards and farm buildings were painted on the airfields to confuse the enemy.
