The Wurlitzer Organ is a type of theater organ that became popular in the early 20th century, particularly in movie theaters. Known for its rich, full sound, it was designed to accompany silent films, providing music and sound effects to enhance the viewing experience. These organs often feature multiple keyboards and a variety of stops, allowing for a wide range of musical expression. The Wurlitzer company, founded by Rudolph Wurlitzer, produced many models, with the most famous being the Wurlitzer 3/11, which has three manuals and eleven ranks of pipes, making it a favorite among musicians and collectors.
