#2. Louis Le Prince
Louis Le Prince is credited for inventing the first ever moving picture film. In 1886, at a workshop in New York City, he developed a 16-lens camera and filmed moving sequences. His work with cameras and film was before the work of the famous inventor Thomas Edison. One day in 1890, while traveling in France to visit his brother, Le Prince mysteriously vanished from a train bound for Paris. Despite investigations, no clues surrounding his disappearance were uncovered. He was never seen again. Some theories that explain his disappearance include suicide, assassination and accidental death by drowning.
