Ricka Löwenthal was born in Bad Kissingen on April 27, 1870 as the second of five children of the tradesman Hermann Löwenthal and his wife Fanny, née Frank and grew up in Promenadestrasse with her parents.

She married the merchant Jakob Mayer who came from the Franconian Sickershausen and moved to Frankfort. There, their two children Friedrich and Rosa were born in 1895 and 1896. In 1919, her daughter Rosa married the merchant Moses Zucker who had been born in Aub near Ochsenfurt. Ricka’s son Frederic emigrated to the United States – presumably in the 1920s – where he married Mary Catherine Hogg in Manhattan in 1931.

Ricka Löwenthal who had been a widow since 1929 lived in Frankfort till May 1934. She succeeded in emigrating to Palestine just like her daughter. At the moment, nothing is known about her further life. Her daughter Rosa died in Jerusalem in 1981.
