The Omohundro Institute of Early American History and Culture (OI) is an independent research organization located in Williamsburg, Virginia, sponsored by the College of William & Mary and the Colonial Williamsburg Foundation. Founded in 1943, the OI supports the scholars and scholarship of vast early America—a term used to describe the capacious histories of North America and related geographies, including foundational histories of indigenous peoples, the scale and impact of transatlantic slavery, and multidimensional European colonization and settlement, from the 1450s to the 1820s. William & Mary and the Colonial Williamsburg Foundation founded the Institute of Early American History and Culture in 1943. In 1996, the name Omohundro was added to the Institute's name in recognition of a private donation from the late Mr. and Mrs. Malvern H. Omohundro, Jr. Source: Wikipedia (en)
