Mary de Morgan (1850-1907) was raised in an exceptional family in Victorian England, by mathematician Augustus de Morgan and spiritualist and social reformer Sophia de Morgan. She was a close friend of William Morris. The body of her work includes short stories, a novel, and essays, but she is mostly known as an author of literary fairy tales. Mary told her tales to her own nephews and nieces, as well as to children of friends and family; among them were the young Rudyard Kipling and his sister. She is unjustly unknown these days, and our hope is to change it.
