Vannevar Bush
The first modern analog computer, the Differential Analyzer could solve certain classes of differential equations.
Vannevar Bush and his colleagues at the Massachusetts Institute of Technology developed the differential analyzer during the early 1930s, with his most successful version becoming operational by 1931.12
This electromechanical analog computer was designed to solve complex differential equations using a sophisticated arrangement of gears, wheels, and steel shafts. Following the success of the 1931 model, Bush oversaw the construction of an even more powerful machine, the Rockefeller Differential Analyzer, in 1935. These devices remained the most powerful computing tools available until they were superseded by digital computers in the mid-1940s.12
