The doctor Fritz Kahl lived in Frankfurt am Main with his wife Margarete and their three sons. He was initially interested in National Socialist ideas. From 1932, he vehemently rejected National Socialism.
In 1938 the Kahl family moved into a building in Frankfurt’s Westend neighborhood, where the medical practice was also located. Numerous Jewish families still lived nearby. Kahl’s practice became a place where persecuted Jewish acquaintances went for help. Fritz Kahl went on treating his Jewish patients. In July 1941 the Reich Medical Council informed him that his additional food rations were cancelled because he had treated Jews.
At the start of 1943, his Jewish patient Eva Müller asked him for help. Her fiancé Robert Eisenstädt needed somewhere to hide. Fritz and Margarete Kahl took him into their home. At the end of February 1943, the Kahls and others helped the couple to escape to Switzerland.
In March 1943, the Kahls also hid Eva Müller’s sister Berta. Fritz Kahl obtained forged identity papers for her escape to Vienna. The Israeli Holocaust memorial center Yad Vashem honored Kahl posthumously as Righteous Among the Nations in 2006.
