Pullman died of a heart attack on October 19, 1897 at the age of 66. Funeral services were held privately at his mansion on Prairie Avenue in the afternoon. The funeral cortege arrived at Graceland Cemetery where elaborate preparations had made. A pit the size of an average room had been dug on the family plot, its base and walls of reinforced concrete 18 inches thick. Into this the lead-lined mahogany casket was lowered, and covered with tarpaper and asphalt. The pit was filled with concrete on top of which a series of steel rails were laid at right angles to each other and bolted together. These rails were embedded in another layer of concrete. It took two days to complete, then sod was put down. These precautions were taken to prevent any desecration of the body — an unfortunate price Pullman paid for his victory in the Pullman strike Ambrose Bierce said It is clear the family in their bereavement was making sure the sonofabitch wasn’t going to get up and come back.
A proposal in 1960 to demolish the community in favor of a new industrial park galvanized residents to form the Pullman Civic Organization (PCO) to support its preservation.  On October 8, 1969, the remaining 300-acre (120 ha) neighborhood was recognized by the National Park Service (NPS) with a listing on the National Register of Historic Places . The next year, it was recognized as a National Historic Landmark District, a site deemed to have "exceptional value to the nation."  The southern portion was locally recognized as a Chicago Landmark on October 16, 1972. A second Chicago Landmark, for the northern portion, was created in 1993, then merged into the other landmark in 1999. The PCO provided grants to help residents restore their houses, and a non-profit called the Historic Pullman Foundation purchased several key buildings for rehabilitation in the 1970s.
