 Scholz was also politically effective in promoting his field. He assembled the “Gruppe von Münster” (later “Schule von Münster”) and encouraged a number of his students to undertake studies in logic and foundational research, placing some of them in academic positions. They obtained important results in the theory of the predicate calculus, the theory of axiomatic systems, metamathematics, semantics and abstraction theory. Among them were Friedrich Bachmann (1909–1982), Albrecht Becker-Freyseng (1907–1976), Gisbert Hasenjaeger (1919–2006), Hans Hermes (1912–2003), Walter Kinder (1909–1998), Karl Schröter (1905–1977), and Hermann Schweitzer (1909–2002). For the publication of this school’s results and related investigations Scholz founded the series Forschungen zur Logik und zur Grundlegung der exakten Wissenschaften (eight issues 1937–1943, n.s. reprinted as Scholz, ed. 1970). Among them is the outstanding book by Heinrich Scholz and Hermann Schweitzer Die sogenannten Definitionen durch Abstraktion with its elaboration of modern abstraction theory using equivalence classes (Scholz and Schweitzer 1935).
