Toshio Kashio: The Man and his Life

Toshio Kashio, Inventor

Born in Tokyo in 1925, Toshio Kashio was captivated by Thomas Edison at age six, and aspired to become an inventor. In 1957, by working to develop a computing device with his older brother Tadao and younger brothers Kazuo and Yukio, he completed the 14-A, the world's first compact all-electric calculator. The four brothers founded Casio Computer Co., Ltd. the same year.

 

During his life,

Toshio created many other inventions including desktop calculators, watches, and electronic musical instruments. He died in 2012 at age 87. In addition to obtaining 313 patents, including joint patents, in his lifetime, Toshio also received many awards including the Tokyo Invention Society Chairman's Award (1958), Japan’s Medal with Blue Ribbon (1984), a Lifetime Achievement Award from the U.S. Consumer Electronics Association (2000), and an honorary doctorate from Tokyo Denki University (2007).

Going from “0” to “1”—Making Something from Nothing. Creating new value out of nothing. The inventor Toshio Kashio took pride in not merely trying to improve an existing product, but in going from "0" to "1" — creating something the world had never seen before.
