Anna Sprengel (allegedly died in 1891), countess of , love-child of Ludwig I of Bavaria and Lola Montez, is a person whose existence was never proven, and who it now seems was invented by William Wynn Westcott to confer legitimacy on the Golden Dawn. In 1901 Mathers, leader of the Golden Dawn, briefly supported the claim of Swami Laura Horos, who had long campaigned for recognition as that countess, to have written to Westcott as Anna Sprengel.
