Task: Question Answering
Input (English): Passage: The film follows Kaspar Hauser, who lived the first seventeen years of his life chained in a tiny cellar with only a toy horse to occupy his time, devoid of all human contact except for a man, wearing a black overcoat and top hat, who feeds him.
One day, in 1828, the same man takes Hauser out of his cell, teaches him a few phrases, and how to walk, before leaving him in the town of Nuremberg. Hauser becomes the subject of much curiosity, and is exhibited in a circus before being rescued by Professor Georg Friedrich Daumer, who patiently attempts to transform him.
Hauser soon learns to read and write, and develops unorthodox approaches to logic and religion; but music is what pleases him most. He attracts the attention of academics, clergy and nobility. He is then physically attacked by the same unknown man who brought him to Nuremberg. The attack leaves him unconscious with a bleeding head. He recovers, but is again mysteriously attacked; this time, stabbed in the chest.
Hauser rests in bed describing visions he has had of nomadic Berbers in the Sahara Desert, and then dies. An autopsy reveals an enlarged liver and cerebellum. 
Question: What is the last name of the person who attracts the attention of academics?
Output (English): Hauser.
