Friedrich Alexander Neubürger
1892 - 1944

Friedrich Alexander, known as Fritz, Neubürger was born on June 29, 1892 in Frankfurt on the Main as the son of the general practitioner Dr. med. Jakob Otto Neubürger (1864-1913) and Henriette Fanny, née Hallgarten (1869-1914). According to Mahlau's Frankfurt address book from 1892, his parents lived at Hochstraße 20 at the time. His father was listed as a doctor, surgeon and obstetrician. Karl's grandfather Dr. med. Theodor Nathan Neubürger (1830-1915) was also listed in this address book with the address Hochstraße 20 and as a doctor, surgeon and obstetrician. His mother Henriette Fanny was the daughter of the Jewish patron Charles L. Hallgarten (1838-1908). The Neubürger family was thus related to the Neisser family, as both Dr. Otto Neubürger and Prof. Dr. Max Neisser were married to a daughter of Charles L. Hallgarten. Fritz Neubürger had a brother named Karl Theodor Neubürger who was two years older. In 1895, his father and grandfather founded the private clinic Dr. Otto Neubürger at Taubenbrunnenweg 7. This was a maternity clinic.

The 1915 address book for Frankfurt on the Main and the surrounding area lists the brothers Karl and Fritz Neubürger as living together at Westendstraße 43, while their grandfather had lived at Hochstraße 20 until his death in December 1915. After the First World War, according to the Frankfurt address books, Dr. Fritz Neubürger lived at Hammanstraße 9 from 1919, i.e. in the immediate vicinity of Holzhausenpark.

In December 1922, Dr. Fritz Neubürger married Eva Jaffé (1892-1944), who lived in Potsdam and had been married to Arthur Israel Heymann (1884-1942) in her first marriage. She came from a Jewish family. Her parents were Prof. Dr. med. Max Eduard Jaffé (1858-1909) from Posen and Marie Elsbeth Werther (1871-1965), who was born in Berlin. Max Eduard Jaffé worked as a senior doctor in the surgical department of the municipal hospital in Posen and was awarded the title of professor in 1902. The Neubürger family lived at Hammanstraße 9 until 1933 and then at Eschenbachstraße 33 in Frankfurt-Sachsenhausen until their emigration in November 1939.

Fritz Neubürger studied political science and was awarded his doctorate in 1913 with a thesis on "Die Kriegsbereitschaft des deutschen Geld- und Kapitalmarktes. A contribution to the critique of our credit organization" at the University of Heidelberg.

In 1922, at the time of his marriage to Eva Jaffe, he was the owner of the Frankfurt Jewish bank "Heidingsfelder & Co." together with Ludwig Heidingsfelder, based at Stein-Weg 9. An entry for this bank can still be found in the Frankfurt address book of 1939. It lists the two owners Ludwig Heidingsfelder and Fritz Neubürger as well as the authorized signatories Hermann Altschüler, Berthold Bär and M. Müller. This bank was actually liquidated in 1938, so that only the liquidation process was carried out afterwards.

The businessman and authorized signatory Hermann Altschüler remained in Frankfurt - unlike Fritz Neubürger - and was deported from there to the Lodz ghetto in October 1941. He perished in July 1942 due to the catastrophic living conditions in this ghetto.

Dr. Fritz Neubürger joined the Frankfurt on the Main section of the German and Austrian Alpine Club in 1922. We find him in the list of members from 1925, but we do not currently know whether he left in 1933 or was expelled. We do not have the relevant sources.

His brother Dr. Karl Neubürger had been a member of the Frankfurt section of the Alpine Club since 1908. He was honored at the annual general meeting in March 1933 for his 25 years of membership in the Alpine Club. We therefore know that his brother did not leave the section immediately after Adolf Hitler came to power.

Dr. Fritz Neubürger emigrated to the Netherlands with his wife Eva Neubürger in November 1939 and lived in Hilversum. He fell into the hands of the Germans and was deported from the Westerbork concentration camp to Theresienstadt in January 1944 and from there to the Auschwitz extermination camp in September of the same year. Fritz Neubürger was presumably murdered there immediately after his arrival. Eva Neubürger was also deported to Auschwitz and was murdered there on October 8, 1944.

His brother Dr. Karl Neubürger emigrated to the USA in August 1938 with his wife Dr. Katharina Neubürger, née Wisbaum, and their three children Maria, Henriette and Otto. He died in Denver (Colorado) in March 1972, his wife also in Denver in September of the same year.
