Walt Disney

He practically invented animation, a pioneer of sound, color, and feature-length animated films. Even stereo sound with the sublime 'Fantasia' (unfortunately not rewarded at the box office, thus stifling all his artistic ambitions in this field). A mention also for the innovative and beautiful Disneyland. Avant-garde and dreamer, we must also remember the futuristic project of Epcot, unfortunately remaining on paper.
