The Boswell Sisters were an American close harmony singing trio of the jazz and swing eras, consisting of three sisters: Martha Boswell (June 9, 1905 – July 2, 1958), Connee Boswell (original name Connie, December 3, 1907 – October 11, 1976), and Helvetia "Vet" Boswell (May 20, 1911 – November 12, 1988). Hailing from uptown New Orleans, the group was noted for their intricate harmonies and rhythmic experimentation. They attained national prominence in the United States in the 1930s during the twilight years of the Jazz Age and the onset of the Great Depression. 　　When the trio formally split in 1936, Connie continued as a solo vocalist in radio, film, and later television for an additional quarter of a century. The trio's "unique singing style and ground-breaking arrangements fused 'blackness' and 'whiteness' in music," and their collaborations with "the preeminent white swing musicians of their day—the Dorsey Brothers, Glenn Miller, Benny Goodman, Artie Shaw—had a profound effect on the development of the big band sound in the 1930s." When assessing their legacy, scholars claim the Boswell Sisters "made 'real' jazz commercially viable, destigmatizing the music and opening its appreciation to the wider American public."
