A fresh life of the noted French scholar, missioner and saint has been very much needed in these recent years, both because of the growing interest attached to the two Roman Catholic orders that arose out of his teaching, and because of the new prominence in international affairs of the part of Africa where he spent his last years among the Tuareg tribes. In most respects this biography is eminently satisfactory. The author has had access to most of the important papers and sources relevant to Foucaul'd life, and develops the chronology of his career systematically and clearly. Foucauld's achievements and importance as an anthropologist, geographer, and linguist, are described, as well as his religious aims and endeavors, and his work is related closely to the social and international developments that were taking place around him. A more critical evaluation of his achievements would seem to lie outside the purpose of the book. This is reading for a wide variety of people interested in one of the significant Christian figures of the early part of this century.
