It remained for Robert Koch in 1882, after years of painstaking investigation, to announce to the world the discovery of a definite bacillus as the causative agent in all forms of tuberculous lesions. Koch isolated, cultivated outside the body, described and differentiated the infective organism of tuberculosis and proved that it could continue to produce the same lesions indefinitely. He showed the presence of the bacilli in all known tuberculous lesions and in tuberculous expectoration, and demonstrated the virulence in sputum which had been dried for eight weeks.
Following directly upon the knowledge of the cause of tuberculosis came the recognition of its curability, and the proper means of its prevention. Although good food and fresh air have always been considered of importance in the treatment of the disease, it was not until the middle of the nineteenth century that anything like systematic treatment was undertaken.
Dr. George Bodingon of Sutton Coldfield, England, wrote an essay in 1840 advocating fresh air treatment. He denounced the common hospital in large towns as a most unfit place for consumptive patients, and established a home for their care, but met with so much opposition that it was soon closed.
In 1856, Hermann Brehmer wrote a thesis on the subject which has been the foundation of our modern treatment. He opened a small sanatorium in 1864. Five years later he established the sanatorium at Goerbersdorf, in Silesia, which eventually became the largest in the world. He advocated life in the open air, abundant dietary and constant medical supervision. He believed that the heart of the large majority of consumptives is small and undeveloped, and that this predisposes them to the disease. In accordance with this theory he put a great deal of emphasis on exercise in the treatment of his patients. He built walks of various grades on the grounds of his sanatorium and installed a system of walking exercise. Patients began with the lowest grade, gradually accustoming themselves to ascend to the highest. Brehmer was himself a consumptive, and was cured by the method he so firmly believed in.
Dr. Dettweiler, who opened the second sanatorium in Germany, at Falkenstein, near Frankfort, was also a consumptive, having developed
tuberculosis during the arduous campaign in the Franco-Prussian War in 1871. He entered the Goerbersdorf Sanatorium as a patient, becoming later an assistant of Brehmer. Dr. Dettweiler laid great emphasis upon rest in treatment.
In 1888, Dr. Otto Walther opened his famous sanatorium at Nordrach in the Black Forest, in Germany.
The first sanatorium for the care of the consumptive in the United States was opened at Saranac Lake by Dr. Edward L. Trudeau in 1884. He was the pioneer of the sanatorium treatment in this country, and an example of what a man, although tuberculous himself, can do for his fellow men. In 1874, a seemingly helpless invalid, he made his home in the Adirondack Mountains. A little more than twenty-five years ago he became the founder of a village now crowded with tuberculous patients. The Saranac Lake institution, which began with one small cottage, has since developed into the best known sanatorium in this country.
In 1891, Dr. Herman Biggs posted the first anti-spitting ordinance in the street railway cars of New York.
Dr. Lawrence Flick brought about the formation of the first anti-tuberculosis society in 1892, and in 1894 the City of New York adopted a law to enforce notification and registration.
