Wilhelm Reich

Reich’s work on char­ac­ter con­tributed to the devel­op­ment of Anna Freud’s The Ego and the Mech­a­nisms of Defence (1936), and his idea of mus­cu­lar armour—the expres­sion of the per­son­al­i­ty in the way the body moves—shaped inno­va­tions such as body psy­chother­a­py, Gestalt ther­a­py, bioen­er­getic analy­sis and pri­mal ther­a­py. see: https://en.wikipedia.org/wiki/Wilhelm_Reich
