Arthur Middleton Young (November 3, 1905 – May 30, 1995) was an American inventor, helicopter pioneer, cosmologist, philosopher, astrologer and author. Young was the designer of Bell Helicopter's first helicopter, the Model 30, and inventor of the stabilizer bar used on many of Bell's early helicopter designs. He founded the "Institute for the Study of Consciousness" in Berkeley in 1972. Young advocated a process theory, which is a form of integral theory. These theories attempt to integrate the realm of human thought and experience with the realm of science so that the concept of universe is not limited to that which can be physically measured. Young's theory embraces evolution and the concept of the great chain of being. He has influenced such thinkers as Stanislav Grof and Laban Coblentz.
