Tracy C. (Tracy Chatfield) Becker

Tracy Chatfield Becker (1855–1935) was an American lawyer and legal writer. Library and archival records consistently identify him as the co-author, with physician Rudolph August Witthaus, of Medical Jurisprudence, Forensic Medicine and Toxicology, a substantial multi-volume reference work published in the 1890s and later preserved by projects such as Project Gutenberg.

That collaboration suggests the role he is best known for today: helping explain complicated medical evidence in legal terms for courts, lawyers, and expert witnesses. The subject matter of his best-known book covers forensic medicine, toxicology, and the use of expert testimony, placing him in an important moment when modern medicine was becoming more central to legal practice.

Biographical details beyond his publications are harder to confirm from readily available reliable sources. A memorial record lists his lifespan as February 14, 1855, to February 20, 1935, and indicates that he was born in Cohoes, New York, and died in California; a Theodore Roosevelt Center record also shows that he was active in public correspondence in the early 20th century.
