Akira Nakashima

Akira Nakashima (中嶋章^[1] or 中島章,^[1] also written as Nakashima Akira,^[1] Nakasima Akira^[1] or Nakajima Akira,^[1] 5 January 1908 – 29 October 1970) was a Japanese electrical engineer of the NEC.

He got a bachelor's degree in electrical engineering from the Imperial University of Tokyo.

Akira Nakashima independenly introduced switching circuit theory in papers from 1934 to 1936,^[2]^[3]^[4]^[1] concurrent with Victor Shestakov and Claude Shannon, laying the foundations for digital circuit design, in digital computers and other areas of modern technology.^[1] However, Shannon's ideas were markedly different in approach and theoretical framework compared to the work of Nakashima, whose work was still based on the existent circuit theory of the time and took a grounded approach, whereas Shannon based his work on mathematics and was far more abstract, thereby breaking new ground and setting up an approach that now dominates modern electrical engineering.^[5]
