A Chicago educator as well as a writer, he is remembered for helping create practical science books for students. His best-known work, A Guide for the Study of Animals (1911), was designed to make zoology more hands-on and approachable in the classroom.

Worrallo Whitney was an American schoolteacher and author who worked in Chicago. Reliable catalog records link him to A Guide for the Study of Animals (1911), a collaborative textbook prepared with Frederic C. Lucas, Harold B. Shinn, and Mabel Elizabeth Smallwood for use in secondary-school biology.
The little that can be confirmed about his life points to a long career in education rather than a large literary career. A later biographical source on his daughter, scholar Lois Whitney, says he taught for more than three decades at Bowen High School and Hyde Park High School in Chicago.
Available records also indicate that he was born in Ohio in 1858 and died in Chicago in 1938. Because detailed biographical information is scarce, he is best remembered today through his contribution to early science education and the textbooks that helped bring animal study into the classroom.
