THE ROCKEFELLER UNIVERSITY 1230 YORK AVENUE NEW YORK, NY 10021 JOSHUA LEDERBERG July 30, 1981 PRESIDENT Dr. Maria New Pediatri€ Endocrine Group The New York Hospital-Cornell Medical Center 525 East 68th Street New York, New York 10021 Dear Maria: My own experience would not lend much support to your speculation about correlating prococity in physical, vis-a- vis intellectual, development; although I recognize that there were some overtones in that direction from the early Terman studies. However, my own speculations aside, I was thinking of where you could find a good cohort for such a study; it occurred to me that the North Carolina School of Science and Mathematics might offer you a nearly unique opportunity to examine a collected cohort as early as the lith grade. I don't know of anything else quite like that, so readily assembled in one place, for earlier ages; but the various societies interested in gifted children might offer far better advice than I could. Do you know the Barany brothers who raced through school and the Rockefeller Ph.D. program? It might be best to attempt to develop case controls on the basis of intra-kindred comparisons; but I don't know what fraction of the youngsters of interest are going to turn out to be only children. If you did not wish to go so far afield, it is possi- ble that some of our special high schools -- like Bronx High School of Science or Stuyvesant High School -- might offer a somewhat less stringently selected group, from which you could still harvest enough instances of what you are seeking. But I expect you would face a lot of political problems trying to do this in N.Y.C. Dr. Maria New Page Two The 1932 composition that I sent you I owe to my mother's saving habits; those genes may have been passed on, but with later onset: I have very few papers that go back before 1940. But since 1947 - to the dismay of many people who have to help me manage those files - I do have 99% of my correspondence and this is an archive of some interest far beyond my own autobiographical curiosity.
