President Dwight D. Eisenhower once praised Walt Disney for his “genius as a creator of folklore.” When Disney died in 1966, the line made it into his obituary, evidence of its accuracy. Folklore, defined broadly, is an oral tradition that stretches across generations. It tells people who they are, how they got here and how they should live in the future. The company Disney created appointed itself keeper of these traditions for Americans, spinning up fresh tales and (more often) deftly repackaging old ones to appeal to a new century.It started with Mickey Mouse, but as his company turns 100, Disney’s legacy — advanced in hundreds of films and shorts and shows, mass-produced tie-in merchandise, marvelous technical advancements, gargantuan theme parks around the world — was the production of a modern shared language, a set of reference points instantly recognizable to almost everyone, and an encouragement to dream out loud about a utopian future. Walt Disney was a man who gazed backward and forward: speaking at the opening of Disneyland in 1955, he proclaimed: “Here age relives fond memories of the past, and here youth may savor the challenge and promise of the future.” But what happens when that promise is broken and the reference points are siloed? When his company struggles at the box office like a regular studio and faces cultural headwinds like any artist?Walt Disney at the opening of Disneyland, extolling the hope of a brighter tomorrow.USC Libraries/Corbis, via Getty ImagesDisney told stories of folk heroes (Davy Crockett, Paul Bunyan), princes and princesses, and even, occasionally, a mouse, all while leading the pack on ever-shifting technologies. (He was, among other things, the first major movie producer to make a TV show.) A sense of optimism ruled Disney’s ethos, built on homemade mythologies. The lessons of his stories were simple, uplifting and distinctly American: believe in yourself, believe in your dreams, don’t let anyone make you feel bad for being you, be your own hero and, most of all, don’t be afraid to wish upon a star. Fairy tales and legends are often disquieting, but once cast in a Disney light they became soft and sweet, their darker and less comforting lessons re-engineered to fit the Disney ideal. It was a distinctly postwar vision of the world.And we ate it up, and we exported it, and we wanted to be part of it, too. “One of the most astounding exhibitions of popular devotion came in the wake of Mr. Disney’s films about Davy Crockett,” Disney’s obituary explained, referring to a live-action 1950s shows about the frontiersman. “In a matter of months, youngsters all over the country who would balk at wearing a hat in winter were adorned in coonskin caps in midsummer.”The coonskin caps were a harbinger of things to come. Halloween would be dominated by princesses and mermaids. Bedsheets and pajamas would be printed with lions and mopey donkeys. Adults would plan weddings at a magical kingdom in Florida. Audiences around the world would join in the legends. Once-closed countries like China would eventually open their doors, leading the company — aware that success in this new market meant fast-tracking children’s introduction to Mickey, Ariel and Buzz Lightyear — to open English-language schools using their characters and stories as the teaching tools. History would show that Eisenhower was onto something when he referred to Disney as a creator, not just a reteller, of folklore.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.
