Wolfgang Metzger

Wolfgang Metzger (born 22 July 1899 in Heidelberg, Germany; died 20 December 1979 in Bebenhausen, Germany) is considered one of the main representatives of Gestalt psychology (Gestalt theory) in Germany.

Metzger's most widely acclaimed work is ''Psychologie: Die Entwicklung ihrer Grundannahmen seit der Einführung des Experiments'' (Psychology: The development of basic principles since the introduction of the experimental method). It portrays systematically the foundations of psychology, including the different kinds of psychological reality, the problems associated with reference systems, order, and much more. Pivotal in its discussions is the cumulative knowledge, at that time, of the entire Gestalt school. Provided by Wikipedia
