Charles Frederick Whittlesey
Charles Frederick Whittlesey (1867–1941) was an American architect best known for his work in the American southwest, and for pioneering work in reinforced concrete in California.
In 1900, at the age of 33, Whittlesey was appointed Chief Architect for the Atchison, Topeka, and Santa Fe Railway. Among many other stations and hotels for the railroad, he designed the El Tovar Hotel, the former Harvey House situated just 20 ft from the south rim of the Grand Canyon in Arizona, United States. It stands at the northern terminus of the Grand Canyon Railway, formerly a branch of the Santa Fe. The hotel is one of only a handful of Harvey House facilities still in operation, and is an example of National Park Service Rustic architecture. The razed Alvarado Hotel in Albuquerque, New Mexico was also his design, with interior work done by Mary Colter.
Whittlesey moved to San Francisco in 1907 and worked mainly there and in Los Angeles, becoming known for his early work in reinforced concrete.
Whittlesey's son Austin C. Whittlesey (1893–1950) was also an architect, apprenticed in the office of Bertram Goodhue for seven years, and was active in Southern California in the 1930s. While working as staff designer for Allison & Allison he designed the 1930 Southern California Edison Building, across the street from Goodhue's L.A. Public Library.

The depot's floor plan is based on the style of early European churches. A tower resembling a Scottish lighthouse rises up from the east side of a multi-arched portico. The beautiful ceilings of the depot are made of stained boxcar siding. The structure was put on the National Register of Historic Places in 1974. In 1977, it was traded to the City of Shawnee and is now open to the public as the Historical Society of Pottawatomie County.
