Zoë Wassilko von Serecki

Zoe Wassilko-Serecki (born July 11, 1897, in Czernowitz, died November 26, 1978, in Vienna) was an Austrian occultist and astrologer. Her paternal grandfather was the Privy Councilor and Governor of the Duchy of Bukovina, Baron Alexander Wassilko von Serecki. The Wassilko family were Austrian Empire-born ethnic Romanian nobility.

In 1900, Stephan and his family moved to Vienna where her father pursued a career in the civil service.

In 1927, she was a founding member of the Austrian Society for Psychical Research. By 1935, she had joined the Nazi party, and in April 1938 correspondence discussing unification of her Austrian society with its German counterpart, she wrote "Poor Winterstein is unfortunately not an Aryan, even in the best possible case he cannot remain the president of the society".

She served as vice-president of the Austrian Astrological Society. That, in turn, inspired Ivan T. Sanderson who became a vocal proponent of the hypothesis. In 1986, years after her death, her "space fish" theory was featured in the writings of Vincent Gaddis.

In 1973, she was recognized by Society for Psychical Research of Great Britain.
