1901–1995
Best known as a science educator who also appears in digital library catalogs as an author, he left a long career in biology teaching and academic life. Reliable public sources on his writing are sparse, so the picture that emerges is of a teacher-scholar whose legacy was strongest in the classroom.

by John Breukelman, Hobart M. (Hobart Muir) Smith
Publicly available records identify him as John William Breukelman (1901–1995). An obituary notice in The American Biology Teacher confirms his dates, and memorial records also reflect that he was known as Dr. John William Breukelman.
The clearest evidence available points to a life centered on biology education rather than a large, well-documented literary career. He is listed in library and bookselling databases as an author, but detailed biographical information about his books, personal life, and broader bibliography is limited in the sources I could confirm.
Because the online record is so thin, it is best to remember him as an educator and academic figure whose name continues to surface through library catalogs and memorial references. That modest digital footprint suggests a legacy preserved more through teaching and professional work than through extensive public biography.
