Fabio Zerpa arrived in Argentina in 1951. Following a short theatrical career, he became increasingly interested in extraterrestrial life, having already studied psychology. After some years of investigation, Zerpa started to give his first conferences at the beginning of the 1960s. In 1966 he created the radio program Más allá de la cuarta dimensión (Beyond the Fourth Dimension). Since then, Fabio Zerpa has reported on more than 3,000 cases of UFO sightings and contact with extraterrestrials. Since 2001 he has been the director of the on-line magazine El Quinto Hombre (The Fifth Man). In December 2005 Zerpa was appointed cultural ambassador of the city of Colonia, in his native country.
