It was run according to humanist and psychological principles, based on Dr. Roberto Assagioli's theory of Psychosynthesis.
During this period Bruno was able to perform extensive research into the horoscopes and psychological profiles of Assagioli's patients, and eventually he developed theories on horoscope interpretation that became the basis for Astrological Psychology, or Huber Astrology.
In 1968, Huber and his wife Louise began to give seminars on the results of their researches, and the Astrological Psychology Institute was founded.
A following was soon established in the locality, and the teaching activities developed apace, going further afield in Switzerland and Germany, and then at international conferences, and in USA, UK, Spain and Brazil.
From 1981, the Hubers were also heavily involved in establishing, organising and presenting at three-yearly World Astrology Conferences in Switzerland.
