H. F. Mumler

Hannah Frances Green Mumler (February 14, 1832 - March 20, 1912) was an American mesmeric physician who professed to use animal magnetism to heal her patients, and formulated a patent medicine known as Mesmerine, a "Great Clairvoyant Blood Remedy." It has been proposed by Felicity Hamer that H. F. Mumler and H. F. Stuart were one and the same, and so played a greater role in her husband William H. Mumler's spirit photography enterprise than is typically supposed, as both owner of the studio where his first spiritual photographs were taken and as a medium in her own right.
