The Milwaukee Theatre began life as the Milwaukee Auditorium, nearly a century ago. “Enrico Caruso sang there before 6,800 people in 1910, a few months after the Auditorium opened Sept. 21, 1909. Doughboys used it for a barracks during World War I. John Philip Sousa and his band played in 1929. The first Milwaukee Sentinel Sports Show was held there in 1940. Martin Luther King Jr. spoke there in 1964.”
