1886–1976
A teacher and co-author who helped bring a more systematic, science-based approach to embalming in the early 1900s, his work sits at the crossroads of anatomy, hygiene, and professional training. Best known for practical manuals written with Albert John Nunnamaker, he remains associated with some of the foundational texts of American mortuary science.

by Albert John Nunnamaker, Charles Otto Dhonau
Working in Cincinnati in the early 20th century, Charles Otto Dhonau is best remembered as a writer and educator in embalming and mortuary science. Library of Congress records identify him as co-author, with Albert John Nunnamaker, of Hygiene and Sanitary Science and Anatomy and Embalming, books published in 1913 and tied to the Cincinnati College of Embalming.
His surviving published work suggests a practical, instructional focus: clear explanations of anatomy, sanitation, and embalming methods intended for students and working professionals. That makes him less a literary author in the usual sense than a specialist teacher whose books helped organize technical knowledge for a growing profession.
Biographical details beyond his publications are sparse, but available records place his life from 1886 to 1976, with roots in Cincinnati, Ohio. Today he is mainly remembered through public-domain editions of his manuals, which offer a window into how embalming was taught and professionalized in the United States a century ago.
