More about this piece can be found on the internet movie data base.
The director is Charles Urban. You may not have heard the name, I had not, but I was actually familiar with some of his work, since he created some of the best known British propaganda movies of the First World War; such as The Battle of the Somme.
Fun fact: He propably made the first ever science documentary, called The Cheese Mites.
You can learn more about this early giant of cinematography on this special website about him.
