Elsa Löwenthal

Elsa Löwenthal was a German-American figure known primarily as the second wife and first cousin of the renowned physicist Albert Einstein. The daughter of Einstein's maternal uncle, her life became inextricably linked with one of the most famous scientists of the 20th century, managing his household and public affairs during his rise to global fame. Her marriage to Einstein coincided with the confirmation of his theory of relativity and their subsequent emigration to the United States.

Early life and family

Elsa Einstein was born in Hechingen, within the Kingdom of Württemberg, to textile merchant Rudolf Einstein and his wife Fanny Einstein. She was the first cousin of Albert Einstein, sharing the paternal grandfather Abraham Einstein. She grew up in a bourgeois Jewish family in Hechingen and later Munich. In 1896, she married merchant Max Löwenthal, with whom she had three daughters: Ilse, Margot, and a child who died in infancy. The family resided in Hechingen before moving to Berlin, where Elsa's marriage deteriorated, leading to a divorce finalized in 1908. Following her divorce, she lived with her two daughters in an apartment on Haberlandstraße in Berlin, where she later reconnected with her cousin Albert, who had moved to the city to take a position at the University of Berlin.

Marriage to Albert Einstein

Elsa Löwenthal renewed her acquaintance with Albert Einstein around 1912, while he was still married to his first wife, Mileva Marić. Their relationship deepened after Einstein moved to Berlin in 1914, and he eventually separated from Marić. Einstein and Löwenthal married on June 2, 1919, shortly after his divorce was finalized. Their wedding took place at Berlin City Hall, with witnesses including Einstein's colleague Max Planck and his friend Heinrich Zangger. The marriage coincided with the historic eclipse expedition led by Arthur Eddington which provided the first empirical evidence for Einstein's general relativity, catapulting him to international celebrity. Elsa actively managed Einstein's chaotic daily life, serving as a protective intermediary with the press, fans, and visitors at their apartment on Haberlandstraße. She frequently accompanied him on his numerous international travels, including celebrated trips to the United States, United Kingdom, Japan, and Palestine, where they met figures like Chaim Weizmann and were received by George V. Despite the public partnership, their private relationship was complex, with Einstein writing candidly about their companionship in letters to friends like Michele Besso and family members such as his sister Maja Einstein.

Later life and legacy

In 1933, following the rise of Adolf Hitler and the Nazi Party, Elsa and Albert Einstein emigrated permanently to the United States. They settled in Princeton, New Jersey, where Einstein took a position at the Institute for Advanced Study. Their home at 112 Mercer Street became a center for scientific and intellectual discussion, frequented by colleagues like Kurt Gödel and J. Robert Oppenheimer. Elsa's health began to decline in the mid-1930s, suffering from heart and kidney problems. She was cared for by her daughter Margot Einstein, who had also emigrated. Elsa Löwenthal died of heart failure on December 20, 1936, in Princeton, New Jersey, and was buried at Cemetery of the Princeton Chapel of Ease. Her role is often noted in biographies of Albert Einstein, such as those by Walter Isaacson and Albrecht Fölsing, where she is portrayed as a stabilizing, albeit traditional, force who handled the practical burdens of his fame. Her correspondence, preserved in the Albert Einstein Archives at the Hebrew University of Jerusalem, provides insight into the social world of one of history's greatest scientists.
