Task: Question Answering
Input (English): Passage: Spoiled playboy Bob Merrick's (Rock Hudson) reckless behaviour causes him to lose control of his speedboat. Rescuers send for the nearest resuscitator, located in Dr. Phillips's house across the lake. While the resuscitator is being used to save Merrick, Dr. Phillips suffers a heart attack and dies. Merrick ends up a patient at Dr. Phillips's clinic, where most of the doctors and nurses resent the fact that Merrick inadvertently caused Dr. Phillips's death. 
Helen Phillips, Dr. Phillips's widow, receives a flood of calls, letters, and visitors all offering to pay back loans that Dr. Phillips refused to accept repayment of during his life. Many claimed he refused by saying "it was already used up." Edward Randolph, a famous artist and Dr. Phillips's close friend, explains to Helen what that phrase means. This helps her to understand why her husband left little money, even though he had a very successful practice.
Merrick discovers why everyone dislikes him. He runs from the clinic but collapses in front of Helen's car and ends up back at the hospital, where she learns his true identity. After his discharge, Merrick leaves a party, drunk. Merrick runs off the road and ends up at the home of Edward Randolph, who recognizes him. Randolph explains the secret belief that powered his own art and Dr. Phillips's success.  Merrick decides to try out this new philosophy. His first attempt causes Helen to step into the path of a car while trying to run away from Merrick's advances. She is left blind as a result of this accident.
Merrick soberly commits to becoming a doctor, trying to fulfill Dr. Phillips's legacy. He also has fallen in love with Helen and secretly helps her adjust to her blindness under the guise of being simply a poor medical student, Robby. 
Question: What is the last name of the person who understands why her husband left little money?
Output (English): Phillips.
