Octavio Medellin (1907-1999) was a painter, sculptor, and educator in Dallas, Texas. Medellin was born in Matehuala, Mexico to parents of Otomi heritage. His family moved to San Antonio, Texas when he was eight years old and he became a citizen of the U.S. in 1939. Medellin attended the San Antonio Art School with classmate Xavier Gonzalez and studied with José Arpa. He also studied at the Chicago Art Institute for a short time. Medellin returned to Mexico in order to study the arts, culture, and history of the country and was greatly influenced by the Mayan and Toltec ruins and artifacts he saw there. He returned to San Antonio in 1931 where he taught at the Witte Museum. Under the sponsorship of Lucy Maverick, an artist he met at La Villita Art Gallery who was involved in the historic preservation of San Antonio, Medellin returned to Mexico a few years later to visit the Yucatan region of the country. In 1966, Medellin opened the Medellin School of Sculpture that is now the Creative Arts Center of Dallas. He also taught at North Texas State University and the Dallas Museum of Art. He completed numerous commissions in the state of Texas including a monument at Calvary Hill Cemetery, a sculpture for the Houston Police Administration, mosaics and carvings for St. Andrew's Catholic Church and St. Bernard Catholic Church, and decorations for the sanctuary in Temple Emanu-el.
Medellin retired from teaching in 1979 and moved with his wife Consuelo to Bandera, Texas. He and his wife had two children, Patsy and Sergio. Medellin died in Dallas in 1999. He was buried in Calvary Hill Cemetery near his commissioned monument, The Garden of the Glorious Mysteries.
