Lake Park; however, due to confusion over its name, it was renamed to Lincoln Park in 1865, in honor of the recently deceased President. Slowly, all of the graves were moved from the cemetery, greatly expanding the park. Haussmann's renovation of Paris and New York's Greensward Plan in the 1850s and 1860s turned new attention to the role that parks can play in urban development. William Butler Ogden, the first mayor of Chicago, advocated for a state bill to create a large park on the South Side. Although initially rejected when proposed in 1868, the Illinois legislature accepted this plan in 1869. The objective was to create a system of parks and boulevards that would form a circle around Chicago. In 1891, J. Frank Foster became the superintendent of the south Chicago park system. He advocated the spreading out of parks into working-class neighborhoods. These generally smaller parks would nonetheless be filled with playing fields and other facilities particularly 'field house' buildings. These facilities would provide all manner of recreation space and services to people of the surrounding neighborhoods. Olmstead's sons, Frederick Law Olmsted Jr. and John Charles Olmsted, designed many of the early neighborhood parks, and these ideas for neighborhood parks influenced national ideas of park design and programming.
