The former Jewish children's home in Fehrbelliner Straße, now the Prenzlauer Berg district center, is an open monument with a historical story. The building was built in 1864 as a residential house. In 1910, it was purchased by the Jüdisches Kinderheim e.V. and converted into a daycare and educational center for Jüdische children and young people. Contemporary witnesses reported that they had attended the after-school care center or kindergarten in the 1920s and 30s. In the 1920s, the children in the home were mainly cared for during the day.

In 1936, the younger daughter Charlotte moved back to the parental home with her two sons Peter (b. 1930) and Werner (b. 1933) after her separation from husband Max Gossels. In the same year Isidor Lewy died and was buried in Weißensee.
