Anton Hellinger (16 December 1925 – 19 September 2019), known as Bert Hellinger, was a Germanpsychotherapist associated with a therapeutic method best known as Family Constellations and Systemic Constellations. In recent years, his work evolved beyond these formats into what he called Movements of the Spirit-Mind. Several thousand professional practitioners worldwide, influenced by Hellinger, but not necessarily following him, continue to apply and adapt his original insights to a broad range of personal, organizational and political applications.
