George Fischbeck, a science teacher turned weatherman who joined KABC-TV in 1972 and spent nearly two decades exuberantly delivering the local forecast, has died. He was 92. Fischbeck, who was known as "Dr. George," died of natural causes early Wednesday morning at the Motion Picture & Television Fund retirement home in Woodland Hills, his daughter, Nancy Fischbeck, said. A trained meteorologist, George Fischbeck was so enthusiastic about his subject that he sometimes forgot to talk about the next day's weather.
