Ida Craddock was an occult sex reformer who wrote about how married couples could spiritualize their unions, giving them control over pregnancy and the right to choose when they had their children. She claimed that she herself had married a spirit or angel from the non-physical realm and that such unions were common in the history of mysticism and religion. Craddock would be persecuted by notorious moralizer, Anthony Comstock, who would try and fail to purge Craddock’s work from the occult record.
