Elsa Einstein (1876-1936)

Elsa Einstein (January 18, 1876 – December 20, 1936) was a German cousin and the second wife of Albert Einstein. Elsa had the surname of Einstein at birth, lost it when she took the name of her first husband Max Löwenthal, and regained it in 1919 when she married her cousin Albert.

Early life
Elsa, the daughter of Rudolf Einstein and Fanny Koch, was born in Hechingen in January 1876.[1] She had two sisters; Paula (c. 1878–c. 1955) and Hermine (1872–1942). Rudolf was a textile manufacturer in Hechingen. During the regular visits with the family in Munich, she often played with her cousin Albert. In her Swabian dialect, she called him "Albertle". After Albert Einstein had left Germany in 1894 to follow his family to Milan, their ways parted.
