"The original pavilion predated the World's Columbian Exposition. It was a product of the South Parks Commission, which was authorized in 1869 to set up a network of parks and boulevards. The boulevards and Washington Park developed fairly quickly, but the commission struggled to gain control of Jackson Park as litigation dragged through the courts. In the 1880s, they decided to develop the section they did control north of 59th Street." [1]
