In 1878, Joseph "Felix" Bey inherited part of Lot 43 on the south side of the square from his father, Casimir Jean Claude Bey, a native of France, and in 1883 he erected a new building there. By 1889, Leon L'Hote and George Muench occupied it with their general merchandise store, which remained in business for 14 years until 1903, while other early occupants included Union Market, Martin and Co., and a saloon. After Joseph died in 1897, his son, Dr. John Emil Bey, managed the building by 1911 and remodeled it for the Electric Theatre, enlarging the theatre space, installing an inclined floor, and adding a stage. The Electric Theatre showed silent movies and world and national news and hosted school graduations, community functions, and visiting talents. By 1913, Dr. Bey oversaw extensive construction and remodeling that added a buff brick front, a hood roof of red Spanish tiles over two new French doors, a peaked brick front topped with a decorative minaret, and tall brick towers topped with ornate urns, while the theatre had bench seating for 500 people and was officially named Bey Auditorium with its name added in terra cotta to the front. In December 1923, Dr. Bey added interior decorations costing $1,000, including 67 paintings by H. E. Springer of Diehlstadt, Missouri, depicting scenes from the Wisconsin Dells, Gulf of Mexico, Rocky Mountains, and one scene from France, with local businesses helping finance the commissioned paintings and having their names appear beside them. By 1925, A. C. Mercier became proprietor, and he and his son, Val Mercier, ran the Electric Theatre until the new Mercier Theatre opened on the west side of the square in 1934, after which the Electric Theatre closed and the building was used for retail businesses. Later occupants included Western Auto, Ted Fricke and Fred Neels Nation-Wide Grocery, Huber House of Color, Golden Needle, Tractors, 15 West Bar and Grill, The Foundry, Southern Roots, and Brass + Bone, the current owner. The Bey family sold the building in August 1983 after 100 years of ownership, and in 2023 Bey Auditorium turned 140 years old.
