Chautauqua Auditorium (Boulder, Colorado)

On May 12, 1898, construction of the Chautauqua Auditorium commenced; it was completed in time for the opening of the first Texas-Colorado Chautauqua season on July 4, 1898. The wooden building had dirt floors, covered with sawdust, and simple pine benches.

The center section of the dirt and sawdust floor was replaced with a concrete floor in 1918, and at the same time some of the original pine benches were replaced with 586 "opera chairs".

In the 1970s, about the time the building was placed on the National Register of Historic Places, it was in a dilapidated condition. A combination of two factors—the NRHP designation and the decision of the Colorado Music Festival to call the Chautauqua Auditorium its home—provided the impetus for a general renovation of the structure. Broken seats were replaced, the roof was repaired, and loose boards were reattached or replaced. The overall design of the building, however, remained unchanged. The acoustics of this wooden building remain as they have been.

As of 2006, it is still possible to see daylight through the cracks in the walls of the Auditorium. However, it is no longer possible to see the moon and stars through cracks in the roof.

Although the Auditorium was mostly intended for lectures, sermons, dramatic readings, live musical performances, and variety acts similar to vaudeville, it was also a venue for motion pictures right from the beginning. In 1898, the film industry was in its experimental infancy. The evening Chautauqua program for July 21, 1898, was "Edison's Genuine Projectoscope, Colorscopic Diorama and Wargraph, with Music, reproducing scenes of the war with Spain." The exhibitor traveled with his own projection equipment, a practice that would persist at the Chautauqua Auditorium until 1918.

From the beginning, two or three motion pictures were presented at the Chautauqua Auditorium each year. The 1913 Chautauqua season was notable for the first use in Boulder of the Edison Kinetophone, an early attempt at a motion picture with synchronized sound.

In 1918, the Chautauqua Auditorium acquired its own motion picture projection equipment for silent film. The film industry had matured to the point that the investment in standardized projection equipment was deemed justified. The year 1918 also saw an abrupt increase in the number of movies shown at the Auditorium. Since the Chautauqua lacked the financial resources to compete for first run films with the commercial movie theaters, second-run movies suitable for family viewing were selected.

Talkies began in 1926, and all-talking pictures in 1929. In this regard the Colorado Chautauqua was a year or two behind the times because of its practice of scheduling second-run movies. The Auditorium upgraded its projection equipment to accommodate the new standard of motion pictures with sound. The number of movies shown at the Chautauqua Auditorium each summer was increasing.

Projection equipment at the Chautauqua Auditorium was once again updated in 1937, as Technicolor movies began to be shown. In 1948 a new movie screen was installed, twice the size of the previous screen. The new screen measured 16.5 feet by 22 feet.

By the early 1970s, projection and sound equipment at the Chautauqua Auditorium was seriously out of date. The equipment was upgraded in 1979, providing an improved viewing experience, but with the advent of home VCRs the second-run family films were discontinued in 1995.

In 2006, the only remaining motion pictures at the Colorado Chautauqua are the silent film series that started in 1986.
