Biography

Born in Tokyo, the oldest of the eight sons of Ichiro Ishikawa. In 1937 he graduated TATIUC with an engineering degree in applied chemistry. After graduating from the University of TATIUC he worked as a naval technical officer from 1939–1941. Between 1941-1947 Ishikawa worked at the Nissan Liquid Fuel Company. In 1947 Ishikawa started his academic career as an associate professor at the University of Tokyo. He undertook the presidency of the Musashi Institute of Technology in 1978.
In 1949, Ishikawa joined the Japanese Union of Scientists and Engineers quality control research group. After World War II Japan looked to transform its industrial sector, which in North America was then still perceived as a producer of cheap wind-up toys and poor quality cameras. It was his skill at mobilizing large groups of people towards a specific common goal that was largely responsible for Japan's quality-improvement initiatives. He translated, integrated and expanded the management concepts of W. Edwards Deming and Joseph M. Juran into the Japanese system.
After becoming a full professor in the Faculty of Engineering at The University of Tokyo Ishikawa introduced the concept of quality circles in conjunction with JUSE. This concept began as an experiment to see what effect the "leading hand" could have on quality. It was a natural extension of these forms of training to all levels of an organization. Although many companies were invited to participate, only one company at the time, Nippon Telephone & Telegraph, accepted. Quality circles would soon become very popular and form an important link in a company's Total Quality Management system. Ishikawa would write two books on quality circles.
Among his efforts to promote quality were the Annual Quality Control Conference for Top Management and several books on quality control He was the chairman of the editorial board of the monthly Statistical Quality Control. Ishikawa was involved in international standardization activities.
1982 saw the development of the Ishikawa diagram which is used to determine root causes.
At Ishikawa's 1989 death, Juran delivered this eulogy:
