Ted Fujita
Tetsuya Theodore "Ted" Fujita was a Japanese American meteorologist who studied storms and tornadoes and visited hundreds of tornado sites to gather data about tornadoes from the aftermath. Fujita, who became known as "Mr. Tornado," developed the Fujita Scale (F-Scale), a six-point scale to measure the strength of tornadoes. Among his other meteorological discoveries were the concepts of downbursts and microbursts, sudden changes in airflow that can be dangerous. (Fun fact! Although he spent much of his life researching and studying tornadoes, he didn't see one in person until he was in his 60s!) (Note: The current EF Scale for evaluating tornadoes is based on the Fujita-Scale.
