At the beginning of the nineteenth century a young medical practitioner, working faithfully in the wards of his hospital in Paris, pitying especially the patients who suffered from pulmonary disease, and realizing how hopeless was their treatment, since medical science knew so little of the real nature of the ailment from which they suffered, invented the stethoscope and established the principles on which modern physical diagnosis is based in a method so complete that after the lapse of three-quarters of a century very little has been added to what was then discovered. This genius was the famed Laennec, of whom we have written in a preceding chapter, who was wont to spend his days walking the wards of the Necker Hospital in Paris, caring more for his poor patients than for the nobility and members of the wealthy classes, who willingly would have taken advantage of his clinical knowledge so conscientiously gained. Laennec made possible progress in medicine that places him among the five or six greatest medical men of all times.

At the end of the nineteenth century a man of about Laennec's age was touched with pity for the sufferings of the poor children whom he saw dying from suffocation because of the ravages of laryngeal diphtheria. Nothing could be done for them except, perhaps, to benumb their senses by means of narcotics, while nurse and medical man stood idly by suffering excruciatingly themselves while their little patients bore all the lingering, awful pains of death by asphyxiation. [{326}] For years Joseph O'Dwyer labored at the problem of relieving these little patients, and finally achieved similar success to Laennec with his stethoscope. The modern doctor, moreover, was quite as patient in his work of research as Laennec, and though his discovery had not so wide an application as the latter's it was accomplished through the same tireless, persevering labor, and through the same instinct of genius that finally led to the culminating invention which no one has been able to improve, and which has made its inventor's name a familiar word to medical men over the world. American medicine has no more shining light than the name of Joseph O'Dwyer, and the record of his simple, sincere, straightforward life, faithful during his successful career to the simple religious principles imbibed in the bosom of an old-fashioned Catholic family, who, during a long career, thought little of self and mainly of the possibilities for good presented by his profession, cannot but prove one of the standard biographies in this country's medical history.

Dr. Joseph O'Dwyer, the inventor of intubation, was born in 1841, in Cleveland, Ohio. Shortly after his birth his parents, who were only moderately well to do, moved to Canada, so that O'Dwyer's boyhood was passed not far from London, Ontario. There he received his early education, and there also, as was the custom in those days, he began his medical studies by becoming a student in the office of a Dr. Anderson. After two years of apprenticeship, he came to New York and attended lectures in the New York College of Physicians and Surgeons, where he was graduated in 1866, at the age of twenty-five. Immediately after graduation he obtained the first place in the competitive examination for resident physician and sanitary superintendent of the Charity or City Hospital of New York City, on Blackwell's Island. Shortly after his appointment [{327}] an epidemic of cholera broke out in the workhouse (under his charge), and Dr. O'Dwyer nobly devoted himself to the care of the patients. While engaged in this work he contracted the disease himself, but fortunately recovered completely without suffering from any of its usual after-effects.

When, not long subsequently, another epidemic of cholera occurred in New York, and a number of cases of the disease were transferred to Hart's Island and there quarantined, volunteers for their medical attendance were asked from among the members of the medical staff of the Charity Hospital. Dr. O'Dwyer was one of the first to come forward and offer his services. Again he contracted the disease, but recovered from it as completely as from typhus. Years afterward he described to a friend his feelings as he lay in one of the hospital tents, the only accommodation that could be provided for him owing to the crowded condition of the wards. His attack was rather severe and yet left him his consciousness, while as he lay expecting death at almost any moment, the thought (as he was wont to relate) sometimes came to him that it was perhaps foolish of him to have volunteered in so dangerous a service. This thought was always put away, however, and he assured his friend that at no time had he ever regretted his exposure to the disease in the cause of suffering humanity. The risks that usually come with professional obligations (it appeared to him) are not to be avoided at the cost of the consciousness of a duty refused.

During his service at the Charity Hospital, Dr. O'Dwyer endeared himself to all those with whom he came in contact. In examination for the position of resident on the Island he had passed first, and during his service there it was generally conceded that he towered above his companions in his efficiency and attention to duty. Some of [{328}] those who were residents with him afterward made names that are distinguished in the history of the practice of medicine in New York City, yet all of them were ever ready to acknowledge that O'Dwyer had been a leader among them in the service. With a very practical turn of mind, he united the capacity for patient work that enabled him to master difficulties, while his devotion to his profession gave him a deep interest in every department of medicine. The foundation of his future success as a practitioner of medicine was laid in these fruitful years of hard work among the poor charity patients of New York City, for whose welfare, as is evident from what we have said, he was ready to make any sacrifice.

After about two years of service on Blackwell's Island, Dr. O'Dwyer, who had attracted no little attention by his faithful fulfilment of duty, was appointed examiner of patients--applicants for admission to the hospitals under the control of the City Board of Charities and Correction. He therefore resigned his position on the Island, and in partnership with Dr. Warren Schoonover opened an office on Second Avenue, between Fifty-seventh and Fifty-eighth Streets. With his colleague, he devoted himself especially to obstetrical practice, in which he had great success, delivering in one year, it is said, over three thousand patients.

In 1872 Dr. O'Dwyer was appointed to the staff of the New York Foundling Asylum, in connection with which his real life-work was to be accomplished. While there Doctors Reynolds and J. Lewis Smith were his colleagues, and all three of them have added no little distinction to American medicine by the careful observations made at that asylum.

At this time one of the most fearful scourges that could afflict a foundling asylum or children's hospital was an epidemic of diphtheria. Those who pretend not to believe [{329}] in the efficacy of the antitoxin treatment of diphtheria should listen to the account given by some of the Sisters, who for long years were in service in the New York Foundling Asylum, of the fear that came over them when it was announced that diphtheria had entered the wards in their charge. It was always certain beyond doubt that this disease would spread very extensively, and, in spite of all precautions and the enforcement of whatever quarantine was possible, the mortality rate would be very high. Usually forty or fifty per cent, of those who were attacked by diphtheria would perish from the disease, nor was it easy to foresee the end of any epidemic.

In not a few cases death took place from that most excruciating of all fatal terminations--asphyxia. The false membrane, characteristic of diphtheria, would form, in a certain proportion of cases, in the larynx and upper part of the trachea of the little patient, the inflammatory swelling that accompanied it further decreasing the naturally small lumen of the child's undeveloped air passages. Gradually dyspnoea would set in, the dreaded croup begin to be heard, and difficulty of breathing developed at times to such a degree that the little one would use every effort to secure breath, the aeration of the blood growing less and less, and cyanosis--that is, an intense blueness of the face and hands--becoming evident, till finally the child died slowly in all the agonies of asphyxiation, while doctor and nurse stood sadly by, absolutely powerless to do anything to relieve the heart-rending symptoms.

About the middle of the nineteenth century tracheotomy--that is, the surgical opening of the trachea, or wind-pipe, below the larynx, for the purpose of admitting air to the lungs through such artificial opening--had been introduced by Trousseau, of Paris. In many cases this afforded relief; [{330}] at least the little patients did not die the awful death by asphyxiation, though not many recovered from the diphtheria or the results of the operation. O'Dwyer himself, when asked what had led him to think of intubating the larynx, said that he had been aroused to experimentation in this direction by the complete failure of tracheotomy during the years from 1873 to 1880 at the New York Foundling Asylum.
