Craig Denney was born in either the U.S. or Canada; his company Moon House was later described as "Canadian," but the truth is unclear.
Welsh describes Denney's company Moon House as "a computerized horoscope service which, for a price, whips out detailed astrological forecasts for individuals and corporations," and by 1975 he claimed to have made $31 million as a result.
Craig Denney was born in 1944-1945, which would have made him roughly 30 or 31 at the time of The Astrologer.
It is also claimed that he died in the mid 80's in Ohio.
