    Almost no young people today know who the cartoon character Oswald the Rabbit is,

but they certainly recognize his successor, Bugs Bunny. Oswald, Bugs, and hundreds of other

characters were created by Walt Disney, perhaps the most famous cartoonist in history.

    Born in Chicago in 1901, Walt Disney always wanted to be an artist. After returning from

World War I, in which he drove an ambulance, Disney worked as a commercial artist. He

enjoyed drawing cartoons more than anything else, and decided to try his hand at a technology

that was new at the time, moving pictures.

   In the 1920's, he produced several films where he made cartoon characters move as if by

magic. The technique Disney used was painstaking. He made hundreds or even thousands of

repeated drawings of the same character. In each drawing, the character was changed just a

bit. A film was taken of the series of drawings, and when it was shown, the characters appeared

to move. The process, called animation, is still used today, although computers have made the

process much easier.

     In 1928, Disney created his most famous character, Mortimer Mouse, who we know today

as Mickey. The mouse starred in a cartoon called Steamboat Willie, which was unusual because

it involved the use of a sound track. Within the next few years, Disney invented many of his other

characters.

    The list of Disney's animation successes is long and memorable. It includes Pinocchio, Dumbo,

Bambi, Cinderella, and Peter Pan. Perhaps his most remarkable animated film is Snow White and

the Seven Dwarfs. Created in 1937, it was an immediate success. Today, more than fifty years later,

it is still one of the most popular films for children.
