The author (now in his 70's) graduated from UCLA with a BS degree in engineering in 1956. He worked in the Aerospace field for 30 years primarily with Advanced Avionics. In addition, he obtained several patents on three dimensional motion pictures for theaters that did not require glasses. He published throughout the world in technical journals, built and demonstrated working prototypes and described the system at seminars. He also consulted for the Battelle Development Corporation. Over a period of 30 years of prophetic bible study, he feels that the complex technical quest to develop the display system experientially helped him focus on the infinitely more important work of the Lord.
