An Academy Award is an award bestowed by the American Academy of Motion Picture Arts and Sciences (AMPAS) to recognize excellence of professionals in the film industry, including directors, actors and writers. The Oscar statuette is officially named the Academy Award of Merit and is one of nine types of Academy Awards.

The formal ceremony at which the Awards of Merit are presented is one of the most prominent award ceremonies in the world, and is televised live in more than 100 countries annually. It is also the oldest award ceremony in the media; its equivalents, the Grammy Awards (for music), Emmy Awards (for television), and Tony Awards (for theatre) are modeled after the Academy.

The AMPAS was originally conceived by Metro-Goldwyn-Mayer studio boss Louis B. Mayer as a professional honorary organization to help improve the film industry’s image and help mediate labor disputes. The Oscar itself was later initiated by the Academy as an award "of merit for distinctive achievement" in the industry.

Olivia de Havilland was born in Tokyo, Japan, to parents from the United Kingdom. Her father, Walter Augustus de Havilland (31 August 1872 – 20 May 1968, aged 95), was a patent attorney with a practice in Japan, and her mother, Lilian Augusta (née Ruse; 11 June 1886 – 20 February 1975, aged 88) was a stage actress who had left her career after going to Tokyo with her husband – she would return to work after her daughters had already won fame in the 40s, with the stage name of Lillian Fontaine. Her parents married in 1914 and they separated in 1919, when Lilian decided to end the marriage after discovering that her husband used the sexual services of geisha girls, but divorce was not signed until February 1925.
