Elizabeth and May Bangs were influential American medium sisters active in the late 19th century, best known for their work with spirit portraits and spirit messages. Operating primarily in Chicago, they claimed to receive drawings and writings from the spirits of the deceased, often producing detailed portraits intended to represent loved ones from beyond the grave.

Their work drew devoted followers as well as critics, and the Bangs Sisters became emblematic of the era’s fascination with visual proof of spirit communication. While skeptics questioned the methods behind their portraits, believers found comfort and meaning in the images. The Bangs Sisters remain significant figures in Spiritualist history, illustrating the powerful emotional role art and imagery played within the movement.
