Despite numerous instances of chicanery, the appeal of spiritualism was strong. Prominent in the ranks of its adherents were those grieving the death of a loved one. Many families during the time of the American Civil War had seen their men go off and never return, and images of the battlefield, produced through the new medium of photography, demonstrated that their loved ones had not only died in overwhelmingly huge numbers, but horribly as well. One well known case is that of Mary Todd Lincoln who, grieving the loss of her son, organized séances in the White House which were attended by her husband, President Abraham Lincoln. The surge of spiritualism during this time, and later during World War I, was a direct response to those massive battlefield casualties.
