Hedy Lamarr (9 November 1913 – 19 January 2000) was an Austro-American actress and mathematician, celebrated for her great beauty, who was a major contract star of MGM's "Golden Age." Mathematically talented, Lamarr and composer George Antheil invented an early technique for spread spectrum communications and frequency hopping, necessary for wireless communication from the pre-computer age to the present day. When she worked with Max Reinhardt in Berlin, he called her the "most beautiful woman in Europe" due to her "strikingly dark exotic looks," a sentiment widely shared by her audiences and critics. She gained fame after starring in Gustav Machatý's Ecstasy, a film which featured closeups of her character during orgasm in one scene, as well as full frontal nude shots of her in another scene, both very unusual for the socially conservative period in which the bulk of her career took place.
Clarence Bull (1896-1979), usually credited as "Clarence Sinclair Bull", was one of the great portrait photographers who worked for the movie studios during the "Golden Age of Hollywood". He was head of the Metro-Goldwyn-Mayer stills department for nearly forty years.
