She became acquainted with the Brothers Grimm in 1813 and told them more than forty tales and variations. Because of Viehmann's Huguenot ancestors, a number of her stories are based on French fairy tales. Wilhelm Grimm wrote that it was an amazing coincidence that he and his brother had met this woman.
