Frederick Haynes Newell

At the same time, he actively assisted Representative Francis G. Newlands (later Senator) of Nevada, George H. Maxwell of California, President of the National Irrigation Association, and others in the preparation and public presentation of various Congressional bills, one of which by the personal efforts of President Theodore Roosevelt became the Reclamation Act when signed by the latter on June 17, 1902. Immediately after that date Mr. Newell was appointed Chief Engineer under Charles D. Walcott, then Director of the U. S. Geological Survey. In 1907 Roosevelt appointed him as a member of the Inland Waterways Commission. Provided by Wikipedia
