Who is this Cristino actor?

The only Cristino I see reference too is a later film director that was born in 1924, after this film was made - who was this Cristino in this film?

Also, very interesting to see that the woman who played Nat-u-rich lived to be 101 years old, in La Jolla California, about 30 minutes away from me! One of the other actresses, I believe who played the love interest to the main character - also lived in La Jolla -
