Stanley Marsh 3 (January 31, 1938 – June 17, 2014) was an American artist, businessman, philanthropist, and prankster from Amarillo, Texas. He is perhaps best known for having been the sponsor of the Cadillac Ranch, an unusual public art exhibit off historic Route 66, now Interstate 40, west of Amarillo. Career In the 1970s, Marsh collaborated with the art group Ant Farm to create the Cadillac Ranch. Marsh has also funded other public art projects in Amarillo, including the "Dynamite Museum," an ongoing project consisting of hundreds of mock traffic signs. These signs, bearing messages such as "Road does not end," "Lubbock is a grease spot," and "I have traveled a great deal in Amarillo," may be found throughout the city of Amarillo. A series of the mock traffic signs are also displayed in Adrian, Texas, approximately 45 miles west of Amarillo. Marsh was said to have wanted the signs to be placed in towns beginning with the letter "A". Additional public art projects sponsored by Marsh were a supposed remains of a giant statue called "Ozymandias" and the "Floating Mesa," a huge natural mesa with a narrow white band wrapped on top of it. Despite the attention of the art projects sponsored by Marsh, critics have called them eyesores with little or no artistic value. In response to the criticism, he is quoted as saying, "Art is a legalized form of insanity, and I do it very well." Marsh appears in documentaries which featured Cadillac Ranch or the city of Amarillo such as The Plutonium Circus and Road Does Not End, a short documentary by a Dallas-based filmmaker about Marsh and the art projects he funded. In 1999, Marsh disrupted a live television broadcast from Amarillo by the cable television network The Weather Channel when he performed a Native American snow dance in front of the cameras. Personal life Stanley Marsh 3's grandfather, Stanley Marsh I, was an oilman who, along with Don Harrington and Lawrence R. Hagy, launched a business that developed oil and gas properties in the Texas Panhandle. While Marsh was the third person in his family named Stanley, he used the Arabic numeral "3" in place of the traditional Roman numeral "III" ("the third"), as he considered the latter to be pretentious. Marsh graduated from the University of Pennsylvania at Philadelphia with bachelor's and master's degrees in economics and history, respectively. Stanley Marsh 3 was
