CHILDREN ABOVE 180 IQ STANFORD-BINET: ORIGIN AND DEVELOPMENT FOREWORD Shortly after the year 1924 Leta S. Hollingworth prepared a manuscript on "Children above 180 IQ (Stanford-Binet)" in which she surveyed the material on the topic available up to that date and added accounts of five cases which she had studied individually. [1] As the years went by she held back the manuscript from publication and one by one she found seven more cases to be included in her list. At the time of her death in 1939 she had begun to revise this manuscript, bringing the survey up to date and adding the new cases. The present book gives as much of this revision from her own hand as is available. The Preface and Chapters 1, 2, and 3 are as she wrote them. The accounts of the first five cases are given just as she originally wrote them up, but to them "editorial supplements" have been added in which an endeavor has been made to present for each case such data as have been found in her files, with little in the way of discussion or interpretation. The seven new cases which the original author had intended to include in the manuscript she had not yet written up. For these, therefore, it has been necessary to study the data she had accumulated for each child, to secure additional data when and where possible, and to present such an account of each as she might herself have written, patterned after her reports of the earlier cases. Much is lost that would have been contributed had the author lived to complete her project. She knew these cases intimately and at first hand. Some of them she had followed for as long as twenty years, taking a personal interest in the individual children and their problems, advising them, assisting them, continuously observing them, and frequently testing and measuring them. Particularly inadequate must be the accounts of the later development of the individuals herein described, for many of the details well known to the author she not committed to paper, since she fully expected to complete the manuscript herself. It is to be regretted that a follow-up study of these recent developments could not have been undertaken, and a hope is expressed that this may yet be done.
