He was born in
Breslau. His father, Emil Beblo, was a secondary school teacher. Fritz was a class comrade of actor
Friedrich Kayssler and author and poet
Christian Morgenstern at the Maria-Magdalenen-Gymnasium in Breslau, where his father also taught. Fritz got his lifelong love of music from his father. His mother took particular care of Christian Morgenstern when he and her son became acquainted with each other. After leaving secondary school in 1883, Beblo first attended the
Technische Hochschule Charlottenburg in
Berlin. Here, he lived in close contact with his school friends Kayssler and Morgenstern. The three of them founded a
cabaret and the regulars' table,
Der Galgenberg (Gallows Hill). As one of the "gallows brothers", Beblo got the nickname of
Stumme Hannes (Silent Hannes). (One of Morgenstern's best-known works is a collection of poems called
Galgenlieder or "Gallows Songs".) Like the future actor, Friedrich Kayssler, Beblo maintained lifelong contact with his school friend from Breslau, Morgenstern. In 1896, Beblo continued his studies at the
Technischen Hochschule Karlsruhe with Professor
Carl Schäfer, a renowned architect. His friendship with the painter
Adolf Erbslöh is from this period. After finishing his studies in architecture, Beblo first went to the fortress
Festung Ehrenbreitstein near
Koblenz as the royal
Prussian site manager and then to
Traben-Trarbach on the
Moselle River. There he participated in building the Moselle Bridge. After passing the examination for
Baumeister (master builder) in 1902, he took over supervision of the building site for the new secondary school in Traben-Trarbach and built an adult education center (
Volkshochschule) according to his own designs. ==1903–1919 in Strasbourg==
