Haloli Q. Richter, 64, a McLean-based astrologer and astrological counselor who lectured widely and also worked as a book reviewer and translator, died Sept. 11 at her home in McLean. She had cancer.

Ms. Richter, an Austrian native, settled in the Washington area in 1962 and operated an astrology practice since 1970.

She taught workshops worldwide, including at a spa in Mexico, and once lectured to a full audience at the Smithsonian Institution's Castle about astrology, art and opera. She was particularly fond of Richard Wagner.

She reviewed books and was an associate editor for Astrology Now magazine, and translated books about astrology and psychology from German into English.

"People here don't understand what astrology is," she told Common Boundary magazine in 1999. "I go to parties and, of course, people ask what I do. When I tell them I am an astrologer, they either say, 'Oh! I read my horoscope in the newspaper every day,' or they walk off. Both parties are ignorant.

"They don't know that astrology was taught in universities until the Age of Reason took over," she said. "That's when alchemy became chemistry and astrology became astronomy, and the soul of the human being was left behind. Now, fortunately, at the end of the Piscean Age and the beginning of the Aquarian Age, there is a reconnection of the soul to science."

Haloli Richter was born in Linz, Austria; she added the "Q" to her name.

By age 5, she said, she was fascinated by symbols in art as a way to understand a deeper meaning. She said she felt she had been an astrologer in a previous life.

As a young woman, Ms. Richter was a champion swimmer in the 100-meter freestyle in Austria.

She moved to the United States after marrying an American in 1959. For years, she ran a group called Quintessence, for women to discuss spiritual matters.

She was a 1990 psychology graduate of Goddard College in Vermont, where she wrote a thesis titled "Bridging Psychology, Astrology and Mythology."

For her astrology practice, she once wrote that she selected clients "who are not sleepwalking through life" and almost always found them through referrals.

The Washington Post asked her to predict Academy Award winners for the 1991 awards ceremony honoring the previous year's films.

Using a formula based on birthdays, she correctly surmised that Kevin Costner and Kathy Bates would win: Costner won for best director (he lost as best actor) for "Dances With Wolves" and Bates for best leading actress in "Misery."

Her marriage to John "Bud" Wallace ended in divorce.

Survivors include a brother, Gottfried Richter of Austria.

Haloli Q. Richter lectured on and taught astrology, and was an editor, reviewer and translator of books on astrology.
