Now old, ill, poor, and largely forgotten, William Freise-Greene was once very different. As young and handsome William Green he changed his name to include his first wife's so that it sounded more impressive for the photographic portrait work he was so good at. But he was also an inventor and his search for a way to project moving pictures became an obsession that ultimately changed the life of all those he loved.
