WILLIAM ARNOLD SR. William Raymond Arnold Sr., 82, of Las Vegas, passed away Aug. 22, 2012. He was born June 25, 1930, in Midland, Texas, and was a Nevada resident for two years. He served in the U.S. Army during the Korean War, and was the retired president and CEO of The Fairfield Company. In the late 1950's Bill was employed by North American Aviation in Downey, Calif. to evaluate capacitors and diodes for the Minuteman Missle Program. In the 1960's, he and his family moved to the east coast, where he was vice president of Scan-Optics, a manufacturer of optical character readers (OCR) in East Hartford, Conn. Bill's next move was to Poughkeepsie, N.Y. in 1969, where he managed a team of scientists and engineers who designed and manufactured the first IBM personal computers. Bill received an Outstanding Achievement Award from IBM for this work. In 1969, he raised seven million dollars on Wall Street to start SEMI (Semiconductor Electronic Memories, Inc.), in Phoenix, to manufacture memories for computers. In 1974, Bill became President of The Fairfield Company, a successful commercial real estate firm in Phoenix, and retired to La Jolla, Calif. in the late 1990's. Bill was a raconteur and life-long learner who will be remembered for his thirst for knowledge. He was a mathematician by education at UCLA under the GI bill. He loved exploring San Diego where he grew up and foreign travel with his wife, of 50 years, Joan. He enjoyed gardening, fine cuisine, art, listening to jazz and classical music, taking photographs and walking around La Jolla. Bill is survived by his sons, Richard Neeley Arnold of Phoenix, William Raymond Arnold Jr. of Eagle Point, Ore., and Robert Roy Reitzen of Los Angeles; granddaughters, Morgan Suzanne Arnold of Phoenix and Jessica Reitzen of Los Angeles; and his former wife, Joan Arnold of Las Vegas. Bill donated his brain to Northwestern University in Chicago, to be used for research into Primary Progressive Aphasia, the cause of his death. Bill's ashes will be scattered at sea from San Diego.
