The developmental history of Adolf runs as follows: His birth was preceded by two miscarriages. The pregnancy was quite normal; confinement easy. When he was a few days old he had some inflammation of the eyes which soon subsided. Never any convulsions. His infancy was normal. He walked and talked early. At three years he had diphtheria badly with delirium for a couple of weeks and paralysis of the palate for some months. After this his parents thought the boy not quite normal. He had slight fevers occasionally. At 9 years he was very ill with scarlet fever. Following that he had some trouble with the bones in his legs. Before he left Hamburg he had an operation on one leg for this trouble which had persisted. (It was quite significant that in our first interview Adolf had told us his leg had been injured by a rock falling on it, necessitating the operation.) Up to the age of 14 this boy, although apparently in good physical condition, used to wet the bed always at night, and sometimes during the day lost control of his bladder. Also lost control of his bowels occasionally after he was 10 years old. He sleeps well, is moderate in the use of tea and coffee, and does not smoke. When young he played much by himself. After coming to this country his chief recreation was going to nickel shows. He was fond of music as a child. He had been a truant in Hamburg. As a young child he was regarded as destructive. The general statement concerning delinquency is that Adolf is the only one of the family who has given trouble and that the father was the first to complain of the boy to the authorities. Before he reported it there had long been trouble on account of frequent changing of employment and misrepresentations. The boy had forged letters to his family and others. In the office of a certain newspaper he once represented himself to be an orphan, and there a fund was raised for him and he was outfitted. The father insists that the boy, in general, is an excessive liar. Further inquiry brought out that other people, too, regarded Adolf as an extreme falsifier. The principal of a school thought the boy made such queer statements that he could not be right in his head. In the office of a clerk of a court he represented himself to be employed by a certain legal institution and demanded file after file for reference. Everybody there was friendly to him at first, but later they all changed their attitude on account of his unscrupulous and constant lying.
