Johnson, after becoming Vice President under John F. Kennedy, purchased a three-story mansion named Les Ormes (The Elms) along 52nd Street NW that had previously been the home of socialite and ambassador Perle Mesta.Miller prohibiting the sale or rental of the property to "persons of Negro blood or extraction, or to any person of Semitic race, blood, or origin, which racial description shall be deemed to include Armenians, Jews, Hebrews, Persians, and Syrians"; the Millers claimed that these covenants reflected the desires of the residents, and not the prejudice of the company or its officers, and anyway could not be eliminated.[5] Although the U.S. Supreme Court ruled such covenants were unenforceable in 1948, they remained in the language of the deeds and were the subject of litigation until the passage of the 1968 Fair Housing Act.Several embassy residences are located in the neighborhood, including the ambassador's houses of South Korea, Canada, Croatia, Mexico, Bahrain, Qatar, Uganda, Chile, Luxembourg, Algeria, Yemen and Estonia.
