Pellegrino Ernetti

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