For the first 19 years of her life, Mary Martell Shaw called Central America home. Then thanks to misrouted luggage, she met the love of her life Rollin H. Shaw, a civil engineer, at a time in when his atomic energy career was taking off. In October 1943, they married in Costa Rica and for the next two decades traversed the country: Hawaii to California to Panama—wherever a project required Ronnie's engineering skills. Mary supported her husband every step of the way, with every new location. As a traditional homemaker of the era, she became adept at raising their four kids while packing boxes, enrolling them in school and setting up a warm home wherever they landed. The move to Las Vegas in September 1964, however, left her a bit challenged: there was a shortage of adequate housing, a concern for where to send her two daughters and two sons to school, and the feeling that they wouldn't be here long. Years later, Mary and Ronnie would retire to the city where their roots ran deepest, Las Vegas. With great wit, Mary recalls the long absences demanded by Ronnie's work with the Atomic Energy Commission. She also tells stories of the great fun they and their fellow Nevada Test Site employees had at parties, of her learning to paint with watercolors, and the pride she has of all her children's successes based on their education in Las Vegas.
