Tetsuya Theodore "Ted" Fujita (藤田 哲也 Fujita Tetsuya?, October 23, 1920 – November 19, 1998) was a prominent Japanese-American severe storms researcher. His research at the University of Chicago on severe thunderstorms, tornadoes, hurricanes, and typhoons revolutionized knowledge of each.
Fujita was born in Kitakyushu, Fukuoka Prefecture, Japan. He studied at Kyushu Institute of Technology and was an associate professor there until 1953, when he was invited to the University of Chicago on the invitation of Horace R. Byers who had become interested in his research, particularly his independent discovery of the cold-air downdraft.
Fujita's best-known contributions were in tornado research; he was often called "Mr. Tornado" by his associates and by the media. In addition to developing the Fujita scale, Fujita was a pioneer in the development of tornado overflight and damage survey techniques, which he used to study and map  the paths of the two tornadoes that hit Lubbock, Texas on May 11, 1970. He established the value of photometric analysis of tornado pictures and films to establish wind speeds at various heights at the surface of tornado vortices. Fujita was also the first to widely study the meteorological phenomenon of the downburst, which can pose serious danger to aircraft. As a result of his work, pilot training worldwide routinely uses techniques he pioneered to provide instruction to students.
Fujita was also largely involved in developing the concept of multiple vortex tornadoes, which feature multiple small funnels (suction vortices) rotating within a larger parent cloud. His work established that, far from being rare events as was previously believed, most powerful tornadoes were composed of multiple vortices. He also advanced the concept of mini-swirls in intensifying tropical cyclones.
The American Meteorological Society (AMS) held the "Symposium on The Mystery of Severe Storms: A Tribute to the Work of T. Theodore Fujita" during its 80th Annual Meeting in January 2000 and also published a special issue of its flagship journal, the Bulletin in January 2001. After Fujita died, Storm Track magazine released a special November 1998 issue, "A Tribute To Dr. Ted Fujita" and Weatherwise published "Mr. Tornado: The life and career of Ted Fujita " as an article in its May/June 1999 issue.
World War II
Residing in Kokura, the primary target of the Fat Man bomb, during the war he was spared by cloudy weather forcing the bombers to move on to the secondary target at Nagasaki. Studying the damage caused by the nuclear blasts led to his understanding of downbursts and microbursts.
