Cleveland Abbe

United States meteorologist

Cleveland Abbe (December 3, 1838 – October 28, 1916) was an American meteorologist and advocate of time zones. While director of the Cincinnati Observatory in Cincinnati, Ohio, he developed a system of telegraphic weather reports, daily weather maps, and weather forecasts.

In 1870, Congress established the U.S. Weather Bureau and inaugurated the use of daily weather forecasts. In recognition of his work, Abbe, who was often referred to as "Old Probability" for the reliability of his forecasts, was appointed the first head of the new service.
