The origination of General Systems Theory is credited to Ludwig von Bertalanffy who, two years after receiving his doctorate from the University of Vienna, published a work in 1932 entitled Theorie der Formbildung. Despite, by his own account, an exposure to and familiarity with the positivism of the Vienna circle, von Bertalanffy was dissatisfied with the reductionist and atomistic forms of explanation which this group asserted is characteristic of scientific explanation. He was particularly unhappy with attempts to pattern explanations of biological phenomena after the model of classical Newtonian physics. In this early work, Models Theories of Development, von Bertalanffy maintained both that the main problem for biology is to discover patterns (laws) which are typical of biological systems and that the discovery of such patterns would produce a major change in the way the world is viewed in general. Von Bertalanffy worked out his proposed model for biological explanation in such subsequent books as Theoretische Biologie and Problems of Life and then in his later years in such works as Robots, Man and Minds and Organismic Psychology and Systems Theory, went on to apply his concepts in a cross-disciplinary way to psychology. Again, by his own account, at a somewhat later period, others, for example the economist Kenneth Boulding and the bio-mathematician A. Rapport, had arrived at, for parallel reasons, certain similar ideas relative to their own disciplines. These individuals together with others formed a joint enterprise which was to result in the interdisciplinary systems movement. Von Bertalanffy stressed the multi-dimension possibilities for fruitful research in a large number of conceptual areas, including the humanities, in his final major work, General Systems Theory Foundation, Development and Applications.
