The Disappearance of Ettore Majorana

Ettore Majorana, one of the most brilliant theoretical physicists of the 20th century and colleague of Enrico Fermi, boarded a ship from Palermo to Naples on March 25, 1938, and was never seen again. He left behind cryptic letters suggesting he was contemplating his own disappearance. Theories include suicide, voluntary exile, or even flight to Argentina. Italian authorities officially concluded in 2015 that he had lived in Venezuela under an assumed name.
