Before Thomas Edison invented filmmaking, there was Louis le France.
He made a number of what we now call movies and then, mysteriously, on September 16, 1890, he disappeared.
The next year, Thomas Edison started his experiments with filmmaking.
In 1898, when Edison sued the American Mutoscope Company,claiming he was the sole inventor of cinematography, the son of le Prince appeared in court and sued for royalties because his father had invented the process.
The court ruled in Edison’s favor. A year later, the court reversed itself.
Edison then revised his patents and went on to dominate the film industry. On September 16, 1897, Louis le France was declared dead and his family never received any royalties from Edison or the film industry.
