author
Best known as a co-author of A Guide for the Study of Animals, this early 20th-century science writer helped shape a hands-on way of teaching zoology. The work invites students to learn by close observation, practical exercises, and direct contact with the living world.

by Worrallo Whitney, Frederic Colby Lucas, Harold Brough Shinn, Mabel Elizabeth Smallwood
Frederic Colby Lucas is chiefly remembered for co-authoring A Guide for the Study of Animals, a classroom text first published in the early 1900s alongside Worrallo Whitney, Harold Brough Shinn, and Mabel Elizabeth Smallwood. Surviving catalog and library records link him to that work, which was written for students studying animal life through structured laboratory exercises.
The book stands out for its practical approach. Rather than treating zoology as a list of facts to memorize, it encourages careful observation and comparison across different kinds of animals. That makes Lucas's contribution feel especially approachable today: his work helped present biology as something to investigate firsthand.
Little biographical information about Lucas himself is readily confirmed from the sources I found, so the focus remains on the book that preserves his name. Even so, that single contribution places him within a generation of educators who helped make natural science more active, curious, and student-centered.
