The first paper listed below (GM 2335) is "the first clear differentiation between the bovine and human types of tubercle bacillus." In the DAB, Phalen writes "Smith ranks in medical history as one of the foremost medical scientists that the United States has produced. His place in American medicine is comparable to that of Pasteur in France and Koch in Germany." Smith (1859-1934) was noted especially for his work on Texas fever, immunization by dead vaccines, differentiation of tubercle bacilli, anaphylaxis, and other related subjects.
