Cleveland was named on July 22, 1796, when surveyors of the Connecticut Land Company laid out Connecticut's Western Reserve into townships and a capital city. They named it "Cleaveland" after their leader, General Moses Cleaveland. Cleaveland oversaw design of the plan for what would become the modern downtown area, centered on Public Square, before returning home, never again to visit Ohio.

In 1885, he moved its headquarters to New York City, which had become a center of finance and business.Cleveland emerged in the early 20th century as an important American manufacturing center.
