Pellegrino Ernetti

Marcello Pellegrino Ernetti (October 13, 1925 – April 8, 1994) was an Italian Roman Catholic Benedictine monk.

The book Father Ernetti's Chronovisor: The Creation and Disappearance of the World's First Time Machine, written in German in 1997 by Peter Krassa claims that Ernetti invented a device that allowed him to witness past events.
