Paul Landon Banfield and his wife, Mary Lee, founded Landon School in 1929. The school’s first location was a former residence in the Sheridan-Kalorama neighborhood of Washington, D.C., now home to the Embassy of Estonia. Banfield moved Landon to its present 75-acre (300,000 m2) campus in Bethesda in 1935. The farmhouse, stables, and barn from the previous use of the Bethesda property still stand on the campus and are used today.
