In this season of ghosts and haunted houses, we’re taking you back to a time when communicating with the dead was a popular way to spend an evening. Séances were the main practice of the spiritualist movement, which is based on the belief that when people die, they survive as spirits, and that we can talk to these spirits with the help of a medium. The movement had its heyday in the late nineteenth and early twentieth centuries, and Jews all over the world, from London to Brooklyn to Cairo, were at the forefront. Scholar Sam Glauber-Zimra explains why spiritualism had such appeal among Jews, what rabbis had to say about it, and why Jewish women were prominent as mediums.
