Frederick Wellington Ruckstull (German: Friedrich Ruckstuhl; May 22, 1853 – May 26, 1942) was a French-born American sculptor and art critic.

In 1885, Ruckstull entered the Académie Julian, and studied under Gustave Boulanger, Camille Lefèvre, Jean Dampt and Antonin Mercié.

As a result of this national exposure, he was commissioned to make an equestrian statue of Major-General John F. Hartranft for the Pennsylvania State University.

In 1893, Ruckstull was appointed to teach modeling and marble carving at the Metropolitan Museum of Art Schools in New York City.

[3] Ruckstull was a founding member of the National Sculpture Society as well as the editor of the conservative magazine Art World, where he wrote under the pseudonym Petronius Arbiter, a reference to the Satyricon.
