Due to the success and the impact of the White City, the men responsible for its creation were called upon when the U.S. Senate decided to improve the District of Columbia to present a more fitting image of America's new international importance at the turn of the century. The McMillan Commission was formed to develop a plan of renovation, and relied on an advisory committee consisting of White City veterans Daniel Burnham, Saint-Gaudens, Charles F. McKim, and Frederick Law Olmsted, Jr., son of the 1893 Fair's landscape engineer. The national focus on urban planning inaugurated the City Beautiful movement, which sought to rebuild the temporary glory of the White City in urban centers across the United States.
