There is some confusion about the years when this quartet was in existence. In a 1949 article on Joseph Fuchs in Saleski's ''Famous Musicians of Jewish Origin'', the following appears on page 339: "His sister, Lillian Fuchs, a gifted violist and composer, became the founder and for 15 years violist of the famed Perolé String Quartet." This information agrees with the first and last dates of Perolé Quartet events (concerts and broadcasts) reported in ''The New York Times'' between 1927 and 1942, a period of fifteen years. In an interview with Dennis Rooney ("Traditional Values"), Lillian stated that she "joined the Perolé Quartet in 1925" and the "ensemble played together for 19 and one-half years." To further complicate the data, the entry for Edgar Leventritt in ''The New Grove Dictionary of American Music'' states that "his support made possible the founding of the Perolé Quartet in 1925." Leventritt's obituary, however, claims "he was the co-founder of the Perolé Quartet in 1927." See ''The New York Times'' (2 June 1939):23.〔Williams, ''Lillian Fuchs'', p. 22.〕
