A: Washington, District of Columbia, United States
In 1943 Mathematical Tables and Other Aids to Computation (MTAC), the world’s first computing journal, began publication in Washington, D.C. At this time mathematical tables prepared by human computers were the primary calculating aid. The journal reported new mathematical tables, and on the new electromechanical and electronic “aids to computation” as they were developed.
By 1960, reflecting the obsolescence of mathematical tables as a result of the development of electronic computing, MTAC changed its name to Mathematics of Computation.
