This collection consists mainly of correspondence between Harold Rubinstein (1891-1975) and Dollie Chareau (1880-1967), and between Michael Rubenstein (1920-2001) and Chareau scholars, including Marc Vellay, Margaret Antalopoulos, and Margaret Tallet. These letters begin with Harold Rubinstein's inquiries regarding Dollie Chareau's family history, but, as a friendship develops between them, the letters become more personal and discuss the Chareaus' life in Paris and subsequent escape from persecution, and their new life in America after 1941. A letter in 1932, written during the construction of the Maison de Verre, documents the intense pressure placed upon architect Pierre Chareau and the worry of his wife on his behalf. After moving to the United States in 1941, letters describe the emigrants' dilemma of belonging and loss. After the deaths of Pierre (1883-1950) and Dollie, Harold Rubenstein's son, Michael, corresponded with several Chareau scholars and followed the exhibitions and scholarly debate surrounding the architect's reputation.

In addition to correspondence, the collection also contains several photographs of Pierre and Dollie Chareau, a monograph entitled "My Father," written by Dollie Chareau, and newspaper and magazine article clippings about Pierre Chareau and his work.
