Until I undertook to gather all available evidence for what I hoped to make a definitive inquiry into the circumstances of Huey Long's assassination, I had no idea of how many gaps there were in my knowledge of what took place. Yet except for the actual shooting, which fewer than a dozen persons were present to see, and for what then took place in the operating room of Our Lady of the Lake Sanitarium, most of what had any bearing on the circumstances took place before my eyes.Consequently I am so deeply indebted to so many who were good enough to fill those gaps with eyewitness reports, that no words of mine could begin to settle the score. Chief among those whose claims on my gratitude I can never wholly acquit are Dr. Cecil A. Lorio of Baton Rouge, one of the only two surviving physicians who played any part in the pre-operative, operative, and post-operative treatment of the dying Senator; Dr. Chester Williams, the present coroner of East Baton Rouge parish, who made it possible for me to see, study and understand the microfilmed hospital chart sketchily covering the thirty hours that elapsed between the time of the shooting and its fatal termination; Col. Murphy J. Roden, retired head of the Louisiana State police, who was the only person to grapple with Dr. Weiss; my friend and for many years colleague, Charles E. Frampton; Sheriff Elliott Coleman of Tensas parish; Chief Justice John B. Fournet of the Supreme Court of Louisiana; and Juvenile Court Judge James O'Connor, who carried the stricken Kingfish to the hospital after the shooting.No less am I under obligations to Earle J. Christenberry,[x] Seymour Weiss, and Richard W. Leche, to whom I owe so much of the information on background elements that alone make intelligible some of the otherwise enigmatic phases of what actually occupied no more than a fractional moment of crisis.My thanks are likewise tendered to Captain Theophile Landry, formerly an officer of the state police; to General Louis Guerre who was that organization's first commandant; to Adjutant-General Raymond Fleming of Louisiana; to Charles L. Bennett, managing Editor of the Oklahoma City Times; and particularly to Dr. James D. Rives and Dr. Frank Loria of New Orleans.To my one time professional competitor but always close friend, Congressman F. Edw. Hebert, I tender this inadequate word of appreciation for the assistance so freely rendered by him in gathering material. To another friend and colleague, Charles L. Dufour, I am deeply indebted for assistance in proofreading.And finally, I am more grateful than I can say to my brother Eberhard, an unfaltering--and what is more, successful--champion before the courts of the principle of press freedom, for advice in preparing the final draft of this manuscript; to LeBaron Barker for invaluable suggestions in revising the original draft; and to all others who, in ways great and small, have been of assistance in making possible the completion of this task.Hermann B.
