First, here are a few facts about Harry Harlow as Blum presents them in this book. (It would have been useful to have a table summarizing this as part of the book itself.) He was born in 1905 in Fairfield, Iowa, to Alonzo Harlow Israel and Mable Rock Israel. He was the third of four sons. One of his older brothers was chronically ill, and Harry says, "I have no memory of partial maternal separation, but I may have lost some percentage time of maternal affection and this deprivation may have resulted in consuming adolescent and adult loneliness." From early on he liked to write poetry and draw pictures. At age 17 he wanted to "be famous," but he made a prediction that he would more likely "end up insane." His parents wanted education for the boys, and three of them, including Harry, attended Stanford; Harry was the only one to graduate from there. Robert, the eldest brother, spent most of his career as chief psychiatrist at the state mental hospital in Warren, Pa.
