“Hutton Peter Gibson (born August 26, 1918) is an American writer on Sedevacantism, a World War II veteran, the 1968 Jeopardy! grand champion and the father of 11 children, one of whom is the actor and director Mel Gibson.
Gibson is an outspoken critic, both of the post-Vatican II Roman Catholic Church and of those Traditionalist Catholics, like the Society of Saint Pius X, who reject Sedevacantism. Gibson is also a proponent of various conspiracy theories. In a 2003 interview he questioned how the Nazis could have disposed of six million bodies during the Holocaust and claimed that the September 11, 2001 attacks were perpetrated by remote control. He has also been quoted as saying the Second Vatican Council was “a Masonic plot backed by the Jews”. Wikipedia.org
