Stephen A. Benton
Over the past 160 years or so, our society has harbored a sub-culture of people so obsessed by a vision of practical three-dimensional image communication that I refer to them as "stereopaths." For most of the 20th century, Edwin Land was the undisputed "king of the stereopaths," which laid the background for his activity in holography. He recalled a childhood replete with stereoscopes and impressive viewcards; his favorites were of grottoes.1 Although his company was founded to pursue the applications of polarizers to night-time automobile safety, the first applications that he actually demonstrated were to 3-D photography, both still and moving, in 1935.
