What is recorded of Elsie Wheeler comes almost entirely through Marc Edmund Jones's own account of her. She worked as a professional clairvoyant medium, seeing paying clients, at a time when she was already, by every description that survives, seriously disabled by arthritis and confined to a wheelchair. Jones described her as having a brilliant and imaginative mind housed in a body that gave her constant pain, and as growing weary of the ordinary run of client questions she was asked, about money and romance, when her gift seemed to her capable of more.
Jones came to know her in 1923 and admired her enough to sponsor his experiment specifically around her ability. When he proposed the undertaking that became the Sabian sitting, he described her as eager to take part precisely because she saw in it a chance to contribute something lasting to astrology rather than another afternoon of routine readings. Beyond this, and beyond the sitting itself, no independent biographical record of her has yet come to light in the sources consulted for this entry. What little else can be inferred comes from the shape of the 1925 material itself: the images she produced range across ordinary domestic scenes, natural imagery and the occasional violent or macabre picture, suggesting a mind that drew as readily on everyday experience as on anything more esoteric. Jones never published a fuller portrait of her beyond this, and no autobiographical writing of her own, if she left any, has been located in the sources reviewed here.
