Alias the Doctor on AllMovie

A Bavarian orphan, raised by a wealthy family, grows up to become a promising physician (Richard Barthelmess). Meanwhile, the privileged young man (Norman Foster) with whom Barthelmess has grown up fails to make the grade at medical school. When Foster bungles an operation, Barthelmess nobly accepts the blame, thereby ruining his own career. The truth comes out after several scenes in which self-sacrificing Barthelmess is pilloried by all those who'd once loved and trusted him. Alias the Doctor reportedly features Boris Karloff as an autopsy surgeon, though in most existing prints the role credited to Karloff is played by John St. Polis.
