First Academy Award

In 1932, Disney received a special Academy Award for the creation of "Mickey Mouse", a series which switched to color in 1935 and soon launched spin-offs for supporting characters such as Donald Duck, Goofy, and Pluto. Pluto and Donald became standalone cartoons in 1937,^[54] with Goofy following in 1939.^[55]Of all Mickey's partners, Donald Duck, who first teamed up with Mickey in the 1934 cartoon, Orphan's Benefit, was arguably the most popular, going on to become Disney's second most successful cartoon character of all time.^[56]

The Disneys' first attempt at pregnancy ended when Lillian miscarried. She became pregnant again and gave birth to a daughter, Diane Marie Disney, on December 18, 1933. The Disneys adopted Sharon Mae Disney (December 31, 1936 – February 16, 1993).^[57]

1937–1941: Golden age of animation

"Disney's Folly": Snow White and the Seven Dwarfs

Walt Disney introduces each of the Seven Dwarfs in a scene from the original 1937 Snow White theatrical trailer.

Following the creation of two cartoon series, in 1934 Disney began planning a full-length feature. The following year, opinion polls showed that another cartoon series, Popeye the Sailor, produced by Max Fleischer, was more popular than Mickey Mouse.^[58] Nevertheless, Disney was able to put Mickey back on top as well as increase his popularity by colorizing and partially redesigning the character to become what was considered his most appealing design to date.^[38]When the film industry learned of Disney's plans to produce an animated feature-length version of Snow White, they were certain that the endeavor would destroy the Disney Studio and dubbed the project "Disney's Folly". Both Lillian and Roy tried to talk Disney out of the project, but he continued plans for the feature, employing Chouinard Art Institute professor Don Graham to start a training operation for the studio staff. Disney then used the Silly Symphonies as a platform for experiments in realistic human animation, distinctive character animation, special effects, and the use of specialized processes and apparatus such as the multiplane camera – a new technique first used by Disney in the 1937 Silly Symphonies short The Old Mill.^[59]

All of this development and training was used to increase quality at the studio and to ensure that the feature film would match Disney's quality expectations. Entitled Snow White and the Seven Dwarfs, the feature went into full production in 1934 and continued until mid-1937, when the studio ran out of money. To obtain the funding to complete Snow White, Disney had to show a rough cut of the motion picture to loan officers at the Bank of America, who then gave the studio the money to finish the picture. The film premiered at the Carthay Circle Theater on December 21, 1937 and at its conclusion the audience gave Snow White and the Seven Dwarfs a standing ovation. Snow White, the first animated feature in America made in Technicolor, was released in February 1938 under a new distribution deal with RKO Radio Pictures. RKO had been the distributor for Disney cartoons in 1936, after it closed down the Van Beuren Studios in exchange for distribution.^[60] The film became the most successful motion picture of 1938 and earned over $8 million on its initial release.

Golden age of animation

Following the success of Snow White, for which Disney received one full-size, and seven miniature Oscar statuettes, he was able to build a new campus for the Walt Disney Studios in Burbank, which opened for business on December 24, 1939. Snow White was not only the peak of Disney's success, but also ushered in a period that would later be known as the Golden Age of Animation for the studio.^[61][62] Feature animation staff, having just completed Pinocchio, continued work on Fantasia and Bambi as well as the early production stages of Alice in Wonderland, Peter Pan and Wind in the Willows while the shorts staff carried on working on the Mickey Mouse, Donald Duck, Goofy, and Pluto cartoon series, ending the Silly Symphonies at this time.^{[clarification needed More info needed on end of the Silly Symphonies to make a new and separate sentence.]} Animator Fred Moore had redesigned Mickey Mouse in the late 1930s after Donald Duck overtook him in popularity among theater audiences.^[63]

Pinocchio and Fantasia followed Snow White and the Seven Dwarfs into the movie theaters in 1940, but both proved financial disappointments. The inexpensive Dumbo was then planned as an income generator, but during production most of the animation staff went on strike, permanently straining relations between Disney and his artists.
