Book excerpt: At first sight it may appear strange that a volume of Progress in Pediatric Surgery should be devoted to the history of our specialty. One assumes that progress is concerned primarily with recent developments whilst history deals with matters of the past. However, in the past there has also been considerable progress in the development of our understand ing of paediatric surgical problems, otherwise we would not have pro gressed to our present achievements. The editors, therefore, do not apologize for compiling this volume but, on the contrary, feel that the publication of this volume is most timely. Modern paediatric surgery has now been practised for three genera tions. The handful of pioneers who were the founders of our specialty worked mainly before the last world war. A few dozen of the inter mediary generation started work immediately after the war, while the new generation who are now dominating our specialty must be counted in thousands. Two factors have radically altered paediatric surgery as practised by the intermediary and the present generation of surgeons.
