Background: Dixy Lee Ray (September 3, 1914 - January 2, 1994) was an American scientist and politician who served as the 17th Governor of the U.S. state of Washington. Variously described as idiosyncratic, and "ridiculously smart," she was the state's first female governor and was governor during the 1980 eruption of Mount St. Helens. She was a supporter of atomic energy. A graduate of Mills College and Stanford University, where she earned a doctorate in biology, Ray became an associate professor at the University of Washington in 1957.
Context: Intrigued by her reputation as a person who could "make science interesting," producers at KCTS-TV, Seattle's PBS affiliate, approached Ray about hosting a weekly television program on marine biology. The show, Animals of the Seashore, was a hit and helped propel her into the public eye beyond campus. Her growing popularity led to the Pacific Science Center extending an invitation to Ray to take over the nearly-bankrupt science museum for an annual salary of $20,000. Ray jumped at the opportunity and immediately began a top-to-bottom overhaul of the center, declaring "I'll be damned if I'm going to become a landlady to a hoary old museum." Under Ray's guidance, the Pacific Science Center was converted from a traditional, exhibit-oriented museum to an interactive learning center.  Ray's hands-on approach to running the Pacific Science Center reflected at every level. She kept a police whistle in her desk that she would use to run off loitering hippies. Jim Anderson, who would eventually teach fisheries science at the University of Washington, recalled a typical encounter with Ray, for whom he worked at the Pacific Science Center in 1968:  Her driving was infamous and my one ride with her, in a three-quarter-ton flatbed truck, was wholly memorable. Admittedly, it was an early Sunday morning, but sliding through stop signs, a few crosswise, was disconcerting at best. The ride went over the top when we reached the Science Center. The lot was full of cars without permits. Trying to fit in a very small space with a large flatbed truck, she dented two cars, broke the taillight off a third, and finally vaporized the rear window of a fourth.  Ray led the Pacific Science Center back into financial solvency. Her aggressive fundraising for the center also helped introduce her to many of the city's most influential citizens, including Senator Warren Magnuson.
