In September 1972, a director of Ricoh Co., Ltd. received an international call. The person who made the call was Robert Noyce, the president of Intel Corporation, an American semiconductor manufacturer, who was said to be the god of semiconductors. The director was surprised by the sudden phone call from such a person, but he was even more surprised by the matter.
``Can you send an engineer named Shima to our company?''
In response to Noyce's unusual request, the director summoned a young man named Shima, who had just joined the company recently, and questioned him.
"Who the hell are you?"
Masatoshi Shima. At the age of 28, he developed the 4004 microprocessor announced by Intel in 1971.
A microprocessor is a chip that is used at the heart of the personal computer that we usually use. The heart is called a CPU (Central Processing Unit), which is generally called a processor, but in the case of a personal computer, it is often integrated into a single chip and is particularly called a microprocessor. In "Next Generation Microprocessor" (Nihon Keizai Shimbun), Mr. Shima
``The invention and development of microprocessors, personal computers, and workstations are about destruction and reform to restore freedom to individuals from the old authoritarian existing system, and the construction and price of a new system with new value. It can be said that it was destruction.”
The invention of the microprocessor was also the beginning of liberalism and individualism in the use of computers.
