Geiger, T. (1928), Führen und Folgen, Berlin: Weltgeist Bücher.

In "Führen und Folgen" ("Leading and Following"), Theodor Geiger examines the relationship between leaders and members of social groups, particularly during times of social and intellectual turmoil. He suggests that group leadership should be understood as a function that serves the group as a whole, rather than as a position of power or authority held by an individual leader.

Geiger distinguishes between different types of leader functions, including the representative and the caring or pastoral type, and different types of organizing leadership, including the creative or "forethinker" type, the organizational or "arranger" type, the technical or "for-doer" type, and temporary leadership roles.

Geiger also discusses the importance of understanding the tasks, legal titles, and methods of selecting leaders, as well as the tensions that can arise between the leader and the group or individual members. Geiger ultimately argues that leadership is a complex and dynamic process that involves a balance between the needs and goals of the group and the individual personalities and abilities of the leader and the group members.
