Pellegrino Ernetti (1925-1994) was a Roman Catholic priest. He joined the Benedictine order at the age of 16. He later became the most famous exorcist from Venice. He was a musician. He wrote books on music theory. He also claimed to have invented a time machine called the Chronovisor. He died at age 68. Before dying he took back his claims about the Chronovisor. However Francois Brune, another priest, and journalist Peter Krassa argued he was pressured into doing this.
