Astrology is complete bullshit, and the leader of the free world being governed by it, as President Reagan was, is a scary thing, though, luckily, those dice rolled well for international relations. The opening of Douglas Martin’s New York Times obituary of Joan Quigley, stargazer to the Reagan White House:

In his 1988 memoir, Donald T. Regan, a former chief of staff for President Ronald Reagan, revealed what he called the administration’s “most closely guarded secret.”

He said an astrologer had set the time for summit meetings, presidential debates, Reagan’s 1985 cancer surgery, State of the Union addresses and much more. Without an O.K. from the astrologer, he said, Air Force One did not take off.

The astrologer, whose name Mr. Regan did not know when he wrote the book, was Joan Quigley. She died on Tuesday at 87 at her home in San Francisco, her sister and only immediate survivor, Ruth Quigley, said.

Mr. Regan said that Miss Quigley — a Vassar-educated socialite who preferred the honorific Miss to Ms. (she never married) — had made her celestial recommendations through phone calls to the first lady, Nancy Reagan, often two or three a day. Mrs. Reagan, he said, set up private lines for her at the White House and at the presidential retreat at Camp David.

Further, Mrs. Reagan paid the astrologer a retainer of $3,000 a month, wrote Mr. Regan, who had also been a Treasury secretary under Reagan and the chief executive of Merrill Lynch.

“Virtually every major move and decision the Reagans made during my time as White House chief of staff was cleared in advance with a woman in San Francisco who drew up horoscopes to make certain that the planets were in a favorable alignment for the enterprise,” he wrote in the memoir, For the Record: From Wall Street to Washington.

In an interview with CBS Evening News in 1989, after Reagan left office, Miss Quigley said that after reading the horoscope of the Soviet leader Mikhail S. Gorbachev, she concluded that he was intelligent and open to new ideas and persuaded Mrs. Reagan to press her husband to abandon his view of the Soviet Union as an ‘evil empire.’ Arms control treaties followed.•
