Her father remarried in 1900 to Eleanor Frances Lewis (1851–1903). Parker hated her father, who physically abused her, and her stepmother, whom she refused to call "mother," "stepmother," or "Eleanor," instead referring to her as "the housekeeper." However, her biographer, Marion Meade, refers to this account as "largely false," stating that the atmosphere in which Parker was growing up was indulgent, affectionate, supportive and generous. Parker grew up on the Upper West Side and attended a Roman Catholic elementary school at the Convent of the Blessed Sacrament on West 79th Street with her sister, Helen, although their father was Jewish and her stepmother was Protestant. (Mercedes de Acosta was a classmate.) Parker once joked that she was asked to leave following her characterization of the Immaculate Conception as "spontaneous combustion." Her stepmother died in 1903, when Parker was nine. Parker later attended Miss Dana's School, a finishing school in Morristown, New Jersey. She graduated from Miss Dana's School in 1911, at the age of 18, according to Authur, although Rhonda Pettit and Marion Meade state she never graduated from either school. Following her father's death in 1913, she played piano at a dancing school to earn a living while she worked on her poetry.
