Eadweard J. Muybridge was a pioneer in the field of motion photography, which greatly contributed to the development of animation. Here's how:

1. Invention of Zoopraxiscope: Muybridge invented a device called the Zoopraxiscope, which was one of the first devices used to project a series of images in successive phases of motion. This was a precursor to the modern motion picture and animation.

2. The Horse in Motion: Muybridge is perhaps best known for his series of photographs called "The Horse in Motion" (1878), where he used multiple cameras to capture the motion of the horse. This was the first time that the idea of creating motion in images was put into practice, and it laid the groundwork for the development of animation.

3. Photographic Studies of Motion: Muybridge spent much of his career studying and photographing animals and humans in motion. His detailed studies of how different species move provided invaluable reference material for early animators.

4. Influence on Others: Muybridge's work had a significant influence on many artists and inventors who came after him, including Thomas Edison and the Lumière Brothers, who were instrumental in the development of cinema and animation.

In summary, Eadweard J. Muybridge's work in motion photography and his invention of the Zoopraxiscope were key contributions to the development of animation.
