Cass Elliot (born Ellen Naomi Cohen; September 19, 1941 – July 29, 1974), widely known as Mama Cass, was an American singer, actress and member of the singing group, the Mamas and the Papas. After the group broke up, Elliot released five solo albums. In 1998, she was posthumously inducted into the Rock and Roll Hall of Fame for her work with the Mamas and the Papas.

Ellen Naomi Cohen was born in Baltimore, Maryland, on September 19, 1941, the daughter of Bess (née Levine; 1915–1994) and Philip Cohen (died 1962). All four of her grandparents were Russian Jewish immigrants. Her family was subject to significant financial stresses and uncertainties during her childhood years. Her father, involved in several business ventures throughout his life, ultimately succeeded through the development of a lunch wagon business in Baltimore that provided meals to construction workers. Her mother was a trained nurse. Elliot had a brother, Joseph, and a younger sister, Leah, who also became a singer and recording artist. Elliot’s early life was spent with her family in Alexandria, Virginia, before the family moved to Baltimore when Elliot was 15, and where they had briefly lived at the time of Elliot’s birth.
