W.D. Bancroft was the first man to seed clouds successfully.
Cloud seeding is an attempt by human beings to have clouds produce precipitation. Typically, humans fly airplanes into the clouds and disperse various chemical compounds to cause the precipitation. Bancroft, who was a professor at Cornell University, was the first man to successfully seed clouds. On January 5, 1923, he succeeded in seeding clouds at McCook Field in Dayton, Ohio.
Bancroft illustrates the important role that Ohioans have played in aviation. With such important names as the Wright Brothers, John Glenn, Neil Armstrong, and numerous others, Ohioans have been at the forefront of aviation history.
