What were walt disney s earliest animation projects?

Quick Answer
Walt Disney’s earliest animation work was done while he ran Laugh‑O‑Gram Studio in the early 1920s, producing a series of short cartoons such as "The Skeleton," "The Trolley Car Tragedy," and "The Haunted House."
Explanation
After moving to Kansas City in 1919, Walt Disney founded Laugh‑O‑Gram Studio, his first venture into animation. Between 1921 and 1923 the studio produced a handful of silent cartoons, many of which are now lost. The surviving titles include "The Skeleton," a playful dance of bones, "The Trolley Car Tragedy," a comedic mishap on a streetcar, and "The Haunted House," a spooky short that used early sound effects. These shorts were hand‑drawn frame by frame and featured a small team of animators, with Disney himself directing the drawings and overseeing the production.
The Laugh‑O‑Gram period was short‑lived; the studio went bankrupt in 1923. Disney then worked for the Film Corp. of America and later for Ub Iwerks, where he continued to develop his animation skills. It was during this time that he experimented with character design and storytelling techniques that would later culminate in the creation of Mickey Mouse in 1928. Although Mickey was not part of his earliest projects, the experience gained at Laugh‑O‑Gram laid the groundwork for Disney’s future successes.
Today, historians regard those early Laugh‑O‑Gram shorts as the foundation of Disney’s animation career. They demonstrate his pioneering use of synchronizing sound, his willingness to experiment with genre, and his commitment to producing short, narrative‑driven cartoons. These projects are often cited as the starting point for what would become the world‑famous Disney animation studio.
