Robert Orville Anderson

Robert Orville Anderson (April 12, 1917 – December 2, 2007) was an American businessman, art collector, and philanthropist who founded Atlantic Richfield Company (ARCO). Anderson also supported several cultural organizations, from the Los Angeles County Museum of Art to ''Harper's Magazine''. He died December 2, 2007, at his home in Roswell, New Mexico.

Anderson turned ARCO into the United States' sixth-largest oil company by the time he left in 1986 due to mandatory retirement. He was by then the largest individual landowner in the United States, with ranches and other holdings in Texas and New Mexico amounting to some and a personal fortune estimated at $200 million.
