Julius Schuster was born in Nordheim vor der Rhön on May 7, 1878 as the son of the cattle dealer Samuel Schuster and his wife Amalie, née Gassenheimer. Nothing is known about his childhood and youth.

He married Hedwig Ida Löwenthal from Altenkunstadt in the Upper Franconian district of Lichtenfels and moved to Coburg with her, where their son Max was born in 1906. In the following years the family moved to Nuremberg. Two years later, Julius Schuster was registered temporarily in Bad Kissingen for the first time. In World War I, he was treated in a hospital in Bad Kissingen for some time because of having been wounded in the war. 

From 1922 till 1938, he regularly earned his living as a businessman in Bad Kissingen during the spa season. In the rest of the year, he continued living in Nuremberg. His wife and his son Max also temporarily lived in the spa town. In the directory of 1928/ 1930, his business is mentioned as “Noris-Magazin” (Noris-storeroom) in Kurhausstrasse 12, access via Lindesmühlpromenade. After his first wife Hedwig had died in June 1933, Julius Schuster married Rosa Blumhof, who was 20 years his junior and came from Grebenau in Hesse in August 1935 and moved to Bad Kissingen after their marriage. In the winter months, they lived in Frankfort/ Main. In October 1938, the couple left Bad Kissingen for good and lived in Frankfort till their emigration. As late as after the beginning of the war – in Spring 1940 – Julius and Rosa Schuster succeeded in fleeing via Genova to the United States where they were first welcomed by Julius’ son Max in New York. Julius’ sister Pauline, m. Sanders, and her husband could also emigrate to New York via Lisbon in June 1941. 

Julius Schuster died in Manhattan in August 1949. His wife Rose outlived him by nearly 50 years. She died in Miami Beach, Florida in August 1996 at the age of 98.
