The creator of Mickey Mouse and Donald Duck, Walt Disney, was a mild-mannered guy who served in the United States military during World War I and World War II and was also an artist. Disney is remembered for creating characters such as Mickey Mouse and Donald Duck. The Red Cross employed him as an ambulance driver during World War I after changing his birth certificate to meet the military service age requirement.
Because of his abilities as a cartoonist and videographer in WWII, he was tasked with creating propaganda cartoons and instructional videos for the war effort, which he accomplished admirably. It served as a kind of foreshadowing of what was to come, in a sense. During that time period, the Walt Disney Training Films Unit was renamed in his honour in recognition of his significant contribution to the industry.
