John Baldwin, Sr., Later founder of Baldwin University (now Baldwin-Wallace College), Berea, Ohio, arrived from Connecticut in 1828 and located in Middleburg Township, Cuyahoga County. Where he purchased a large tract of land (now part of Berea), and established his home. In 1842, near his home, he noticed a thin slab of stone, which had a gritty nature and led him to believe that it would be suitable for grindstones. He took it home and shaped it into a grindstone with an old axe and after using it, found it had excellent sharpening qualities, much better than any stone he had seen in Connecticut. He started turning grindstones out on a lathe, which he operated with waterpower. For the next decade, he turned out grindstones made of Berea Grit. During the years 1850 to 1870, Berea Sandstone came into use as a building material and was recognized as a standard among the building stones of the country.
