Masaru Ibuka was a Japanese electronics industrialist and co-founder of Sony.
In 1946 Ibuka and Akio Morita co-founded Sony Corporation, originally named Tokyo Telecommunications Engineering Corporation (prior to 1958). Ibuka was instrumental in securing the licensing of transistor technology to Sony from Bell Labs in the 1950s, thus making Sony one of the first companies to apply transistor technology to non-military uses. Ibuka served as president of Sony from 1950 to 1971, and then served as chairman of Sony between 1971 and 1976, when he retired from the company.
Ibuka was awarded the Medal of Honor with Blue Ribbon in 1960, and was decorated with the Grand Cordon of the Order of the Sacred Treasure in 1978 and with the Grand Cordon of the Order of the Rising Sun in 1986. He was further decorated as a Commander First Class of the Royal Order of the Polar Star of Sweden in that year, named a Person of Cultural Merit in 1989 and decorated with the Order of Culture in 1992.
Ibuka also authored the book Kindergarten is Too Late (1971), in which he claims that the most significant human learning occurs from birth to 3 years old and suggests ways and means to take advantage of this. The book's foreword was written by Glenn Doman, founder of The Institutes for the Achievement of Human Potential, an organization that teaches parents about child brain development. Ibuka and Doman agreed that the first years of life were vital for education.
