Ohio, rich in history and proud of the accomplishments of some of the nation’s greatest scientific pioneers, is honored with a new 37-cent U.S. stamp commemorating its bicentennial, released Saturday.

Originally Ohio was composed of land ceded to the United States after the Revolutionary War. The Northwest Territory, as it was called, included present-day Illinois, Indiana, Michigan, Ohio and Wisconsin. In 1787 Congress enacted a plan to organize and govern this large area.

The next year its first permanent settlement was established in Marietta, Ohio. On Feb. 19, 1803, President Thomas Jefferson approved Ohio’s constitution, and on March 1, 1803, Ohio became the 17th state admitted to the Union.

Ohio has been the birthplace of seven presidents — including Ulysses Grant and William McKinley — and has produced such pioneers as Thomas Alva Edison who was born in 1847 in Milan, Ohio. The state also lays claim to the Dayton bicycle shop owned by the Wright brothers, where they conducted many experiments in flight.
