The Thomas Jefferson Foundation, originally known as the Thomas Jefferson Memorial Foundation, is a private, nonprofit 501(c)3 corporation founded in 1923 to purchase and maintain Monticello, the primary plantation of Thomas Jefferson, the third president of the United States. The Foundation's initial focus was on architectural preservation, with the goal of restoring Monticello as close to its original appearance as possible. It has since grown to include other historic and cultural pursuits and programs such as its Annual Independence Day Celebration and Naturalization Ceremony. It also publishes and provides a center for scholarship on Jefferson and his era.
