Heym's own attitude towards his parents was paradoxical; on the one hand he held a deep affection for them, but on the other he strongly resisted any attempts to suppress his individuality and autonomy.

Other members of this Club included Kurt Hiller, Jakob van Hoddis, and Erwin Loewenson (also known as Golo Gangi); often visiting were Else Lasker-Schüler, Gottfried Benn, and Karl Kraus.

Although the Club had no actual stated objective, its members all shared a sense of rebellion against contemporary culture and possessed a desire for political and aesthetic upheaval.

The Club held "Neopathetisches Cabaret" meetings in which members presented work, and it was here that Heym first gained notice.

In January 1911, Ernst Rowohlt published Heym's first book and the only one to appear in his lifetime: Der ewige Tag (The Eternal Day).
