1868–1915
Best known for clear, practical science textbooks, this early-20th-century writer helped bring anatomy, hygiene, and zoology into the classroom in a direct, accessible way.

by Alvin Davison
Alvin Davison was an American science educator and textbook author born in 1868 and died in 1915. Library and archive records link his name to a steady run of school and college texts published in the early 1900s, especially in physiology, hygiene, anatomy, and zoology.
Among the works associated with him are The Human Body and Health, Health Lessons, Practical Zoölogy, and Mammalian Anatomy, with Special Reference to the Cat. These titles suggest a writer focused on explaining living systems clearly for students, with an emphasis on practical health knowledge as well as laboratory-based biology.
Reliable biographical detail beyond his dates and published works is limited in the sources I could confirm here, so it is safest to remember him primarily through the books themselves: classroom texts designed to make science understandable and useful for young readers and teachers of his time.
