Joseph Plateau was a Belgian physicist and inventor, born on October 14, 1801. He is best known for his work in the field of optics and for inventing the phenakistoscope, an early device that created the illusion of motion through a series of images. This invention laid the groundwork for the development of animation and motion pictures. Plateau's research also contributed to the understanding of persistence of vision, a phenomenon that explains how the human eye perceives a series of still images as continuous motion. His contributions to science and art have had a lasting impact on both fields, influencing future generations of artists and filmmakers.
