High Quality Content by WIKIPEDIA articles! Contactees are persons who claim to have experienced contact with extraterrestrials. Contactees have typically reported that they were given messages or profound wisdom by extraterrestrial beings, and that they were compelled to share these messages. These claimed encounters are often described as ongoing, but some contactees claim to have had as few as a single encounter. As a cultural phenomenon, contactees perhaps had their greatest notoriety from the late 1940s to the late 1950s, but individuals continue to make similar claims in the present, such as Swiss cult leader Billy Meier. Some have shared their messages with small groups of followers, and many have issued newsletters or spoken at UFO conventions.
