The Gasworks and all the perceptual cells relate back to my trying to convey the joy of discovery about light that I experienced in the psychology of perception. They are not like the more classical works that I usually do. These are works that point directly to how I learned to see light this way and think about light this way. James Turrell is one of the most celebrated American artists working today. Born in California in 1943, he grew up with an enduring love of aviation and the sky, as well as a fascination with light. His Quaker background also substantially formed his approach to life and art, with its emphasis on silent access to the "light within." From age six, Turrell was urged by his grandmother to "go inside and greet the light" at Quaker meetings. In the early 1960's, Turrell studied perceptual psychology at Pomona College, taking additional classes in other scientific disciplines, such as mathematics, geology and astronomy.
