Hideo Itokawa

Japanese: 糸川英夫 - いとかわひでお

Born: July 20, 1912, Tokyo, Japan
[Died] February 21, 1999. Nagano, Maruko, space engineer. A leader in the development of the pencil rocket, he is called the father of rocket development in Japan. Born in 1912 in Azabu-ku, Tokyo City, Tokyo Prefecture (today Nishi-Azabu, Minato-ku, Tokyo). After graduating from the First Tokyo Municipal Junior High School (today Kudan High School) and the former Tokyo Senior High School, Science Class A, he graduated from the Department of Aeronautics, Faculty of Engineering, Tokyo Imperial University in 1935. After graduation, he joined Nakajima Aircraft Company and participated in the design of the Japanese Army's Type 97 Fighter, the G7M Fighter "Hayabusa", and the G7M Fighter "Shoki". In 1941, he became an assistant professor at the Second Faculty of Engineering, Tokyo Imperial University, and in 1948, he became a professor. In 1954, he organized the AVSA (Aviation and Supersonic Aerodynamics) research group at the Institute of Industrial Science, University of Tokyo. In April 1955, he conducted a horizontal launch experiment of the Pencil Rocket in Kokubunji, Tokyo, and from August 1955, he conducted flight experiments at Michikawa Beach in Akita Prefecture. In August of the same year, he launched the Baby Rocket. In 1956, he launched the Kappa Rocket. From then on, in the 1960s, he led the development of the Lambda Rocket. In 1967, he left the University of Tokyo and established the Institute of Tissue Engineering, which marked his departure from the front lines of space development. He worked to put systems engineering into practice in society, and later devoted himself to friendship with Israel. In his later years, he moved to Maruko-machi, Nagano Prefecture (today's Ueda City), and died in a hospital there in 1999 of multiple cerebral infarctions. In 2003, the target of the asteroid probe Hayabusa was named Itokawa after him. In 2012, to commemorate the 100th anniversary of his birth, a bronze statue was erected at the Uchinoura Space Center and an unveiling ceremony was held.
