Slater, John (1861–1932)
American clairvoyant who, for 50 years, gave remarkable
demonstrations of reading sealed letters and giving names,
data, and specific information on deceased people from the
platform. He traveled all over the United States and attracted
big audiences. In 1930, he established his right to function as
a medium in Detroit, Michigan. A clergyman had him arrested
for making predictions, then a statutory offense, but he won the
case with costs and continued his work thereafter undisturbed.
He later moved to San Francisco.
