Career
Gunzburg developed the Natural Vision stereoscopic 3-Doctorate system. After pursuing his education at University of California, Los Angeles and Columbia University, Gunzburg became a Hollywood scriptwriter at Metro-Goldwyn-Mayer Studio in the 1940s before abandoning the business to focus on the development of 3D filming in the 1950s. While watching footage of home movies which he had filmed in 3D, he was inspired to pursue the development of a new 3D technique for the film industry.
Although the film was a critical disaster, it was an enormous commercial success.
Natural Vision was then used to film House of Wax with Vincent Price and The Charge at Feather River. In 1972 Gunzburg sued Warner Brothers regarding both films claiming that he had not been paid according to his contract.
The success of Natural Vision led to a lucrative contract with Polaroid wherein Gunzburg maintained exclusive rights for a year to sell the special glasses required to view the 3D films. Gunzburg died of cancer in Beverly Hills, California in 1991.
