The people on this page were influential in their countries and local organizations, people who carried the torch of astrological knowlege to new generations and who furthered the growth of our field. For the most part, the biographical information and chart data comes from the person who suggested their names.

Jeannine Akimowa: Hellen Vos writes, "It is with great sadness that, on behalf of the members of her emailsite: the Isis-Sabaka-list, I nominate Jeannine Akimowa for a place on your list. Jeannine was born on October 7, 1959 at 8:38 am local time in Utrecht, The Netherlands (52N06 5E07) and died on March 28, 2002 at 8:12 am local time in Ede. She worked as a full time project manager in automation, but was fascinated by psychological astrology since school time.

"She studied all by herself and, as a consequence of her Venus conjunct Pluto in Virgo, became absorbed in depth psychology. It was Zane Stein's Chironlist that gave her the opportunity to contact international professional astrologers, which inspired her to specialize in studying Pluto and Chiron. This resulted in the development of spiritual astrology by means of the Black Moon. Her Isis-Sabaka-list enabled astrologers from all over the world to share their knowledge concerning the Black Moon. It proved to be a success. In the meantime, Jeannine developed an absolute, even stubborn, vision on behalf of the Black Moon. Her conclusions were admired and resisted. She aimed at publishing a book regarding this matter, but unfortunately she was not allowed to. While working on it, she fell ill and died at the very early age of 42. At the time of her death, Pluto who had always fascinated her, made a transit conjunction to her Sagittarian Moon."

Wim Smits: He was suggested by Tees Reitsma, who writes, "Wim was born on 16 February 1917 at 06:52 GMT in The Hague, The Netherlands, as a true Aquarius with Mercury, Venus, Uranus, Ascendant, Sun and Mars in Aquarius respectively. As a matter of fact, I am writing this exactly during his Uranus-return.

"At the early age of 15 he was already studying astronomy with a selfmade telescope, and during his life he not only added microscopic studies and astrology (since 1943), but also metaphysics, several foreign languages, and above all life itself and people. Wim loved people and astrology and he never needed an astrowatch to be able to tell you exactly which sign was rising or culminating at a certain time: he 'lived' astrology.

"Wim also loved books and collected and studied them during his whole life, to the extent that they filled up the entire attic of his home as well as his own room from the floor to the ceiling, leaving only a small space for his bed. He wrote many interesting astrological articles that were published, but had trouble finding a publisher for his book: "Astrologie en Wereldvoorstelling" (= Astrology and Worldview), so it was eventually published by the magazine "Astro-Kring" - as promised him shortly before he died.

"Wim could always be found at all astrological meetings, no matter which group had organized it, where, or what astrological system was being used, and he usually brought a special book as gift for someone at the same time.

"The result of this was that his death on 4 June 1985 was felt by all astrological organizations in this country as the great loss of 'our Wim'. We then realized that this quiet Aquarius had shown us all the true meaning of brotherhood, and that you can belong to many different astrological organizations at the same time."
