Garnet Wolesey Jex (October 19, 1895[1] – September 21, 1979[1][2]) was an American artist and historian.

While completing his master's degree, he worked as an art editor for the journal Nature.

[6] Jex also known for his paintings of dinosaurs and other Permian Age animals including those created for dioramas at the Dallas Exposition on behalf of the United States Texas Centennial Commission, and at the National Museum of Natural History for which he painted a 15 foot long mural.

Although a flood destroyed the canal in 1924,[9] Jex's works remain as a visual record of the once commercially important structure.

[10] While many of Jex’s works are held in private collections, others can be found on public display at the Smithsonian American Art Museum[11] and at Harpers Ferry National Historical Park.
