Cleveland Abbe (born December 3, 1838, New York City, U.S.—died October 28, 1916, Chevy Chase, Maryland) was an American astronomer and meteorologist who assisted in the development and growth of the United States Weather Bureau, later renamed the National Weather Service.
Trained as an astronomer, he was appointed director of the Cincinnati (Ohio) Observatory in 1868. His interest gradually turned to meteorology, however, and he was appointed the assistant to the chief signal officer in 1871. In this position, in which he was given the task of developing regular weather forecasts, Abbe became one of the first civilians working on behalf of the Signal Corps, a branch of the U.S. Army responsible for what would later become the civilian-managed U.S. Weather Bureau (see also weather forecasting).
