Dutch philosopher, mathematician, astronomer, astrologer and anthroposophist.
Elisabeth Vreede came into contact with Theosophy in her home growing up. She was interested early on in the starry sky, read the works of Camille Flammarion and learned French at the same time. At the University of Leyden she studied mathematics, astronomy, philosophy (especially Hegel) and Sanskrit. She was also actively involved in student life, founding a boat club, and was a council member of the students’ union.
Her first meeting with Rudolf Steiner took place at the Theosophical Congress in London in 1903. Vreede was leader of the mathematics and astronomy sections in the Goetheanum in Dornach from 1926 till 1935. In her capacity as leader of the Mathematical-Astronomical Section she wrote a monthly letter, then available by subscription, about both modern astronomy and classical astrology in the light of spiritual science. The letters included explanations of the fundamentals of astronomy and discussions of astrology in the modern world, with reference to such topics as nutation, precession of the equinoxes, comets, solar eclipses and lunar eclipses and the meaning of the Christian holidays such as Easter and Whitsun. The Letters in English translation were published in 2007 with the title Astronomy and Spiritual Science.
In 1935 the separation within the Anthroposophical Society took place and she was expelled from the executive council and excluded along with her long-time friend and co-member, Dr. Ita Wegman from the board of directors. She was also cut off from the observatory and archives that she herself helped assemble.
The last years of her life became more lonely. She was cut off from her friends abroad by the War. The death of Ita Wegman at the beginning of March, 1943, was a great shock for her.
