His biggest passion is still always reading, and the most important thing in the world to him are historic, biographic, and geographic dates. He knows the birth and death years of many German Kaisers, also many generals, poets, philosophers, mostly also birthdays and places of birth; furthermore the capitals of most states, rivers on which they lie and the like. He knows decisions of the beginning and end of the Thirty Year's and Seven Year's Wars, of the main battles of these and other wars. From statements of the mother, everything he picked up on without outside help, through the diligent study of a "patriotic calendar" and similarly discoverable literature in the house, also through the deciphering of monument inscriptions in the cities (for which he especially has passion). When two different pages with two 12-digit numbers were shown to him in succession, [the numbers of] which differed by one of the middle digits, he read them as far as the billons and could then, without looking at the pages again, with certainty, specify wherein the difference lay. [e] Dr. Placzek et al. who earlier observed the boy, the definitive impression prevailed of a specially aroused, rapid, and sharp-thinking and, at the same time, a benign, quite loveable child. With the parents and particularly with the mother he's involved with the greatest affection. [f] An _Obersekundaner_ is a pupil in seventh year of a German secondary school. "Gymnasium" here means secondary school. [g] "Now, almost 17 years old, he is an intelligent, young man, equipped with an admirable memory, full of knowledge; a young man easily getting noticed, orienting, who, although in his way preferred before his contemporaries, has proven [to have] a humble, lovable nature." PART II TWELVE CASES NEW TO LITERATURE CONCERNING TESTED CHILDREN CHAPTER FOUR CHILD A Child A is a boy, born June 18, 1914. He was brought by his parents to Teachers College, Columbia University, in the latter weeks of 1920, for mental tests. This was on the advice of the principal of the school A attended, for the boy was a school problem. He did not adjust himself readily to the work of the classroom in the second grade where he was at that time placed, at the age of 6 years 6 months. The school had found A ready for work beyond the second grade in reading and arithmetic, but because of his age and size it had decided to place him in second grade. The record made at that time and subsequently reads as follows: FAMILY BACKGROUND A is descended from German Jews on both sides of his family. His parents are not related by blood so far as can be known. He is of the third generation to be born in the United States. The paternal grandfather is living [[1920]] and well, a tailor by trade. He is "very handy" in making helpful devices to use in his shop. The paternal grandmother is living [[1920]] and well, a competent housewife, who has evinced no noticeable intellectual interests.
