John William Mauchly was born on 30 August, 1907, in Cincinnati, Ohio, in the family of Sebastian J. and Rachel Scheidemantel Mauchly. The father, Sebastian Mauchly, whose grandparents had emigrated to Ohio from Zürich, Switzerland, in 1839, was a high-school science teacher, who went on to receive his PhD in physics from the University of Cincinnati. When John was 8, his father received an appointment as a chief physicist at the Carnegie Institute of Washington, D.C., in the newly established Department of Terrestrial Magnetism. This position, and his apparatus, enabled John’s father to discover the diurnal variation in the Earth’s magnetic field, a discovery for which he secured a considerable reputation.
Yet, if a commitment to science was one of the early elements of John’s socialization, he was also moved by the heady materialism of the 1920s. Although scientists in the United States were not yet a class unto their own, membership in an elite institution such as the Carnegie Institution enabled the Mauchlys to enjoy middle-class lifestyle, they carved out for themselves in a modest four-bedroom, one-bath frame house in the comfortable suburb of Chevy Chase, Maryland. John’s mother, Rachel Mauchly, was a strong woman, who enjoyed the gay lifestyle of the 1920s. She had attended the regular meetings of the local Women’s Club, hosted some of its luncheons, and held informal hen parties with her new friends and social acquaintances. The mother worked hard to cultivate her son’s interests. She arranged for the obligatory piano lessons, chided him for his penmanship, and saved up for the annual family vacation out at the Jersey shore.
