PREFACE v 



G. Harding, president of the United States and honorary vice- 

 president of the National Tuberculosis Association. 



In preparing the history, I wrote first an introductory part, out- 

 lining in a general way the beginning and development of the 

 tuberculosis movement in general and the National Tuberculosis 

 Association in particular, and including a section on the Sixth 

 International Congress and a chapter on the work of the various 

 state associations. The remaining parts of the book deal with the 

 proceedings of the various annual meetings of the Association, 

 the biographies of the officers, lists of their contributions to tuber- 

 culosis literature, a description of the war work in tuberculosis of 

 the Surgeon Generals of the U. S. Army, the U. S. Navy, and the 

 U. S. Public Health Service, a list of books, pamphlets, and 

 leaflets issued by the Association, and lastly, the tuberculosis 

 bibliography of the author. In this way the history has become 

 not a mere chronicle of events alone, but a record of the men who 

 brought these events to pass.
