THE EARLIEST DEMONSTRATION OF THE TUBERCLE BACILLUS IN THE UNITED STATES  Baldwin1 writes that "Edward L. Trudeau was one of the earliest in America to appreciate the discovery made by Koch in 1882. He did not have the advantage of first hand contact with Koch as did Welch, Prudden and H. P. Loomis. Nevertheless he quickly acquired the technic of staining the bacillus from Prudden and Hodenpyl of the old laboratory of the College of Physicians and Surgeons in New York, as has been so graphically told in his 'autobiography.' It is related that the late Surgeon General George M. Sternberg was believed by his wife to be the first to stain the tubercle bacillus in America. However, Dr. T. Mitchell Prudden visited Koch's laboratory in 1885 and brought back a thorough knowledge of the methods of the master."According to Winslow,2 the elder Flint brought the news of Koch's discovery to Welch, who before many weeks were past succeeded in staining the bacillus by Koch's methods and also demonstrated it to his colleagues.
