Here’s an article from the December 26 1933 edition of the Toronto Daily Star that describes a prediction that turned out to be extremely incorrect.
Blanche de Paunac was known as La Mysterieuse, and had been performing for at least twenty years. This photo of her apparently dates to 1912, and a French magazine from 1935 lists her as appearing at 51 Rue Geoffrey-Saint-Hilaire between 2 and 6 pm every day (the reference is at the top left of page 10 of the PDF). I couldn’t find out anything else about her.
Her oracular powers, arising from her self-induced hypnotic sleep, also got it wrong about King Alfonso XIII – he never regained the Spanish throne.
