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.
