The drawings for the Plan of Chicago were executed by Ben E. Holden, Clarence E. Howard, Chester M. Davison, Chris U. Bagge, and Leo Strelka. Mr. Holden was identified with the study of the general plan and the park system, both in general and in detail; Mr. Howard with the Center of the City and the Railroads; and Mr. Davison with the treatment of the Lake Front. The plans for the Civic Center and for Grant Park were studied by Fernand Janin of Paris, who came to Chicago in 1908 for that especial purpose. The renderings by Jules Guerin were made during extended visits to Chicago in 1907, and again in 1908. The work of both Mr. Guerin and Mr. Janin appears over their names. The Sanitary District Map of the City of Chicago has been used in compiling the plan drawings. Plate XVII is compiled from plans published in “Les Transformations de Paris.” THE COMMERCIAL CLUB OF CHICAGO ORGANIZED 1877; UNITED WITH THE MERCHANTS CLUB, 1907.
