Lorado Zadok Taft was an American sculptor, writer and educator. Part of the American Renaissance movement, his monumental pieces include, Fountain of Time, Spirit of the Great Lakes, and The Eternal Indian. His 1903 book, The History of American Sculpture, was the first survey of the subject and stood for decades as the standard reference. He has been credited with helping to advance the status of women as sculptors.

Fountain of Time, or simply Time, is a sculpture by Lorado Taft, measuring 126 feet 10 inches (38.66 m) in length, situated at the western edge of the Midway Plaisance within Washington Park in Chicago, Illinois, in the United States. The sculpture is inspired by Henry Austin Dobson's poem "Paradox of Time". Its 100 figures passing before Father Time were created as a monument to the 100 years of peace between the United States and the United Kingdom following the Treaty of Ghent in 1814. Father Time faces the 100 from across a water basin. The fountain's water was turned on in 1920, and the sculpture was dedicated in 1922. It is a contributing structure to the Washington Park United States Registered Historic District, which is a National Register of Historic Places listing.
