Desch and Mumma’s Electronic Accumulator

The next major leap in computing technology involved the use of vacuum tubes as on/off valves. This enabled calculations to be made electronically rather than mechanically, which resulted in a significant increase in calculating speed.

The first use of the vacuum tube in a computing device was in 1938, when Joseph Desch (1907-1987) and Robert Mumma (1905-) built a machine they called the Electronic Accumulator. This machine primed the world for the true first-generation computers, and would be the dominant switching technology for the next 20 years.
