While an extremely modest man himself, and one of very {349} few words, Dr. O'Dwyer delighted in teaching others anything he felt that he knew well himself. His conduct with regard to the teaching of intubation was especially admirable. He was ready to show any serious-minded physician just how the operation was accomplished, and many a young doctor obtained precious training in the exercise of the rather difficult manipulation involved in placing a tube in a child's larynx from the hands of O'Dwyer himself. He never lost patience with the awkward ones and never seemed to consider that too many calls were made on his time. He might easily have made money on the operation or the instruments, but deemed such considerations unworthy of his professional dignity. Personally he was a very reticent man, but, as a number of friends have said of him, "he made every word count;" and those who knew him best justly appreciated the expression of an opinion from him, since it was always sure to be the fruit of mature consideration and the result of personal clinical experience, usually extending over long periods. The opinion held of Dr. O'Dwyer by his colleagues in the profession--and, be it well understood, there is no more searching appreciation of practical methods and theoretical opinions than that obtained by brother-physicians--is the best possible tribute to his greatness as an investigator, his honorableness as a practitioner, and his distinction as a man. We quote the summing up of his character given by Dr. Northrup, who had been his colleague for a score of years at the New York Foundling Asylum, and whose paper on the subject was read before the New York Academy of Medicine shortly after O'Dwyer's death: "What the world knows of O'Dwyer," said Dr. Northrup, "is his genius as an inventor, his achievement in adding a great operation to the equipment of the profession, and thus {350} making the most conspicuous real contribution to medical progress within the last fifty years. This the world knows and has acknowledged. To us there is another and a pleasant duty to testify, that with this genius there was all that goes to make a man. His home life, his religious life, his civic life, his professional relations with both colleague and patient, his hospital relations, were such as befit a high-principled man. As highly as we esteem him as an inventor and genius and practitioner of wide knowledge, as much as we valued his superior medical judgment, we would write upon the monument of his achievements, 'O'Dwyer the Man.'" In a previous passage of his address before the Academy, Dr. Northrup had said:
