According to the video below, the inventor of the first digital computer was John V. Atanasoff. This video tells the story of Atanasoff’s work on creating the Atanasoff-Berry computer. Atanasoff wanted a shortcut to the long calculations needed for theoretical physics. He worked on ideas for a faster calculation system during 1935 and 1937. His idea was to create a chain of mechanical calculators. The idea failed, so in 1937, Atanasoff decided to build a new machine using a binary system, choosing digital over analog.
