Orthon is a Venusian who contacted George Adamski telepathically on November 20, 1952 in a California desert. Orthon communicated with Adamski about the dangers of nuclear war and left behind footprints with mysterious symbols on them.
On 20 November 1952, George Adamski and several friends were in the Colorado Desert near the town of Desert Center, California, when they purportedly saw a large submarine-shaped object hovering in the sky. Believing that the ship was looking for him, Adamski is said to have left his friends and to have headed away from the main road. Shortly afterwards, according to Adamski's accounts, a scout ship made of a type of translucent metal landed close to him, and its pilot, a Venusian called Orthon, disembarked and made contact. Adamski claimed that the people with him also saw the Venusian ship, and several of them later stated they could see Adamski meeting someone in the desert, although from a considerable distance.
Adamski described Orthon as being a medium-height humanoid with long blond hair and tanned skin wearing reddish-brown shoes, though, as Adamski added, "his trousers were not like mine." Adamski said Orthon communicated with him via telepathy and through hand signals.
During the conversation, Orthon purportedly warned of the dangers of nuclear war, and Adamski later wrote that "the presence of this inhabitant of Venus was like the warm embrace of great love and understanding wisdom." Adamski claimed Orthon had refused to allow himself to be photographed, and instead, had asked Adamski to provide him with a blank photographic plate, which Adamski claimed he had given Orthon. George Hunt Williamson (a contactee and Adamski associate) also claimed that after Orthon left, he was able to take plaster casts of Orthon's shoe imprints. The imprints contained mysterious symbols, which Adamski said was a message from Orthon.
Orthon is said to have returned the photographic plate to Adamski on 13 December 1952; when developed it was found to contain new strange symbols. It was during this meeting that Adamski is said to have taken a now famous photograph of Orthon's Venusian scout ship using his 6-inch (150 mm) telescope.
