Joseph Jacinto "Jo" Mora (October 22, 1876 – October 10, 1947) was a Uruguayan-born American cartoonist, illustrator and cowboy, who lived with the Hopi and wrote extensively about his experiences in California. He was an artist-historian, sculptor, painter, photographer, illustrator, muralist and author. He has been called the "Renaissance Man of the West".
Mora was born on October 22, 1876 in Montevideo, Uruguay. His father was the Catalonian sculptor, Domingo Mora, and his mother was Laura Gaillard Mora, an intellectual born in the Bordeaux region of France. His elder brother was F. Luis Mora, who would become an acclaimed artist and the first Hispanic member of the National Academy of Design. The family entered the United States in 1880 and first settled in New York City, and then Perth Amboy, New Jersey. Jo Mora studied art at the Art Students League of New York and the Cowles School in Boston. He also studied with William Merritt Chase. In Boston, he worked as a cartoonist for a newspaper called the Boston Evening Traveller and then worked for the Boston Herald.
In the spring of 1903, Mora arrived in Solvang, California. He stayed at the Donohue Ranch. He made plans to travel to the Southwest to paint and photograph the Hopi. He spent time at the Mission Santa Inés; those photographs are now maintained by the Smithsonian Institution. Mora visited many Spanish missions in California that summer by horseback. He followed the "Mission Trail", also called the "Kings Highway".
