Ida Dehmel (née Coblenz) was born in Bingen am Rhein, the daughter of a prosperous Jewish family, whose genealogy on her father’s maternal side can be traced back to the year 1735. Her father Simon Zacharias (1836–1910) became a partner in the wine merchant firm of Joseph Philip Meyer, marrying Meyer’s daughter, Emilie (1840–1878). The couple had five children: Elise or “Alice” (1864–1935), Julie Hedwig (1865–1935), Cornelius (1866–1922), who died in Worthing, Sussex, Ida (1870–1942) and Marie Louise, or “Lulu” (1877–1892). Emilie’s early death in 1878, six months after a complicated childbirth, meant that the family was raised in a patriarchal milieu that was dominated by firm rituals, decorum and etiquette. However, their stern upbringing was relieved by the close proximity of their late mother’s parents, the Meyers, who resided nearby in a large family house on the Marktplatz (market square). In the unpublished autobiography of her youth, which she started in 1901 (entitled Urschrift) and which was reworked during the 1920s and in 1940 as a novel (entitled Daja), Ida fondly recalled her grandmother, who was Paris-born and who took a keen interest in her grand-daughter’s well-being (Daja, 7–9, in HH 1970, 3).
