I T IS most fitting at this time that we, as a group of orthodontists, should pause, consider, and pay deserved tribute to Dr. Edward Hartley Angle in this, the one-hundredth anniversary year of his birth. This should be done with the deepest gratitude, as there is little in dental history to indicate that there would now be world-wide specialization and organization by capable orthodontists, except for the genius of this man. It has been said, ((Genius consists of 3 per cent inspiration and 97 per cent perspiration,” but it is impossible in all eases to determine the relative values of these two requisites. In this instance, the history of the profession reveals that, through hundreds of years, many men with fine, educated minds and lofty purposes had left meticulous records of their words and ideas. However, they failed to pass on to their successors any definite and workable systems of procedure in orthodontic practice. After these many comparatively fruitless generations, there suddenly appeared on the scene, in 1878, a young graduate, Dr. Edward H. Angle, who already had a true and comprehensive vision of the past, present, and future of orthodontic problems. In that vision, there were revealed to him the tremendous potentialities for human good that had been wasted through failure to treat malocclusion understandingly. Also, it was obvious to him that this was due to neglect on the part of schools and appropriate organizations to select and train men to perform this very important, undeveloped dental service. Later he stated: “In 1880 I had become very much interested in orthodontia, and I came to believe that some time, perhaps after a long time, orthodontia would be practiced as a specialty, for it seemed to me that its importance entitled it to a closer study and application in practice and that only would enable anyone to become sufficiently familiar with its principles and master its technique, to overcome its difficulties and be successful in its practice. This conviction has constantly grown upon me in the years that have followed. In 1896, I advocated it,s teaching and practice as a specialty in a paper read before the Western Pennsylvania Dental ASSOciation. ” It was in accordance with this educational concept of the problem that Dr. Angle spent much time in teaching in dental colleges and in writing papers and books. His hope was that the schools in time would come to see the wisdom of increasing their efforts in this respect. However, the results were so disappointing after seventeen years of such sacrifice that he resigned in
