While belief in an afterlife is a cornerstone of many ancient and modern religions and cultures worldwide, the idea that it’s possible to communicate with the dead never reached the same level of acceptance. But, for a period of about a century, beginning in the 1840s, sending messages between the human and spirit worlds was popular not only as a religion, but also as a pastime.
Though a few 18th-century European thinkers toyed with the concept of a potential connection between science and the supernatural, the new religious movement known as modern Spiritualism got its start in upstate New York in 1848. That’s when two sisters, Margaret and Kate Fox, became locally and later, internationally famous after claiming they could get in touch with people beyond the grave. For some, the work of mediums like the Fox sisters was purely entertainment. But for others, it became a religion, and is still practiced as one in a few remaining communities today.
Spiritualism’s popularity waxed and waned throughout the remainder of the 19th century and the first decades of the 20th century, predictably surging following massive losses of life, like the Civil War, World War I and the 1918 Flu Pandemic. And although the Spiritualist movement never completely faded out, it didn’t hold the same appeal after World War II. But for close to 100 years, Spiritualism attracted people from every part of society—including celebrities.
Here’s a look at eight famous figures who, at some point in their lives, believed it was possible to communicate with the dead.
