Otto Schwabe (born on October 2 1894 in Hanau; died on September 22 1937 ibid) was a German Jüdian physician well known in the city of Hanau, who met his death under unexplained circumstances after being arrested by the Gestapo . Schwabe came from a Jewish family long established in Hanau, whose origin was the house first mentioned in 1689 Zum Schwaben in Hanauer Judengasse (today Nordstraße).

According to the Ravenstein plan of 1861, the house Klostergasse 59 was located exactly opposite  the exit of the street " Am Judenbrückchen ". In 1937, during the redevelopment of Frankfurt's Old Town, the houses in the northern part of Klostergasse were demolished. In 1944, during an air raid in 1944, the area around the Klostergasse was völlig destroyed.
