Through biography one learns the history of mankind, since history is but a recounting of the acts of individuals and their influences on one another. Professor Sigerist begins his account with the mythical Imhotep and Asklepios, follows with Hippocrates, and then discusses biographically all the great figures of medicine whose names are associated with periods of progress. The style of the book is literary, marked by an excellent vocabulary and by a sense of humor and of the drama. Each of the sketches is illustrated with an excellent portrait. It is fortunate that this book is soon to be made available in an English translation.
