George Calvert (planter)

George Calvert (February 2, 1768 – January 28, 1838), was a plantation owner and slaveholder in late eighteenth- and early nineteenth-century Maryland. His plantation house, Riversdale plantation, also known as the Calvert Mansion, is a five-part, large-scale late Georgian mansion with superior Federal interior, built between 1801 and 1807, and was designated a National Historic Landmark in 1997. Calvert's wife, the Belgian-born heiress Rosalie Stier Calvert, was an indefatigable correspondent whose letters, titled Mistress of Riversdale, The Plantation Letters of Rosalie Stier Calvert, was published by the Johns Hopkins University Press in 1991. The letters range in date from 1795 to 1821, and illuminate the life of the Calverts' plantation household during the events leading up to and during the War of 1812.
