Ferdinand Peck, a Chicago businessman, incorporated the Chicago Auditorium Association in December 1886 to develop what he wanted to be the world's largest, grandest, most expensive theater that would rival such institutions as the Metropolitan Opera House in New York City. He was said to have wanted to make high culture accessible to the working classes of Chicago.
