Perinatal medicine came into being during the middle of the 20th century, when human medicine entered the intrauterine space.This book presents in an integrative way the history of the still young speciality. The main emphasis is on the time period up to the early 70swhen the major changes e.g. Cardiotocography took place. Both scientific precursors and later developments are mentioned shortly, when appropriate. Many chapters of this book represent a unique eyewitness report by Prof. Erich Saling, the so-called "Father of Perinatal Medicine".
