The Chicago Plan Commission is a commission implemented to promote the Plan of Chicago, often called the Burnham Plan. After official presentation of the Plan to the city on July 6, 1909, the City Council of Chicago authorized Mayor Fred A. Busse to appoint the members of the Chicago Plan Commission. On November 1, 1909, the City Council approved the appointment of 328 men selected as members of the Commission—men broadly representative of all the business and social interests of the city. Charles H. Wacker was appointed permanent chairman by the Mayor, and served until 1926, when he was succeeded by James Simpson.
