George Washington Van Tassel (March 12, 1910 – February 9, 1978) was an American contactee, ufologist and author. Early life Van Tassel was born in Jefferson, Ohio in 1910, and grew up in a fairly prosperous middle-class family. He finished high school in the 10th grade and held a job at a small municipal airport near Cleveland; he also acquired a private pilot license. At age 20, he moved to California, where at first he worked as an automobile mechanic at a garage owned by an uncle. While pumping gas at the garage, he met Frank Critzer, an eccentric loner who claimed to be working a mine somewhere near Giant Rock, a 7-story boulder near Landers, California in the Mojave Desert. Frank Critzer was claimed by others to be a German immigrant During World War II, however, he was born in the US. Critzer was under suspicion as a German spy and killed himself by a dynamite explosion during a police siege at the Rock in 1942. Upon receiving news of Critzer's death, Van Tassel applied for a lease of the small abandoned airport near Giant Rock from the Bureau of Land Management, and was eventually given a Federal Government contract to develop and maintain the airstrip. Van Tassel became an aircraft mechanic and flight inspector who at various times between 1930 and 1947 worked for Douglas Aircraft, Hughes Aircraft, and Lockheed. While at Hughes Aircraft he was their Top Flight Inspector. In 1947, Van Tassel left Southern California's booming aerospace industry to live in the desert with his family. At first, he lived a simple existence in the rooms Frank Critzer had dug out under Giant Rock. Van Tassel eventually built a new home, a café, a gas station, a store, a small airstrip, and a guest ranch beside the Rock. Integratron George Van Tassel started hosting group meditation in 1953 in a room underneath Giant Rock, excavated by Frank Critzer. That year, according to Van Tassel the occupant of a space ship from the planet Venus woke him up, invited him on board his space ship, and both verbally and telepathically gave him a technique for rejuvenating the human body. In 1954, Van Tassel and others began building what they called the "Integratron" to perform the rejuvenation. According to Van Tassel, the Integratron was to be a structure for scientific research into time, anti-gravity and at extending human
