A. (Adolph) Eichhorn

Adolph Eichhorn (1875–1956) was a veterinary scientist and medical writer whose work centered on animal disease, bacteriology, and biological therapeutics. Records of his publications place him with the United States Bureau of Animal Industry, where he was identified in different years as a bacteriologist, assistant in pathology and bacteriology, senior bacteriologist, and later chief of the pathological division.

He wrote and co-wrote a wide range of technical and practical works, including studies on glanders, anthrax vaccination, tetanus antitoxin, Malta fever, meat hygiene, and milk hygiene. He also published A Treatise on Veterinary Biological Therapeutics and contributed to veterinary pharmacology and therapeutics texts, showing a career that balanced research with clear guidance for working veterinarians.

Later sources connect him with Lederle Antitoxin Laboratories as director of its veterinary department, suggesting that his career moved from federal scientific service into applied laboratory and publishing work. A clear confirmed portrait was not available from the sources I could verify.
