A hands-on educator from Cleveland, he wrote with the clear, practical style of someone who wanted students to learn by building. His best-known work turns toy making into a lively lesson in craft, design, and classroom creativity.

by David M. Mitchell
David M. Mitchell is known for Advanced Toy Making for Schools, a manual first published in 1922. The book presents toy making as both a creative craft and a teaching tool, with detailed plans and an emphasis on practical shop skills.
The text identifies him as an instructor in manual arts at Willson Junior High School in Cleveland, Ohio. That background helps explain the book’s direct, useful tone: it feels written for teachers and students who were meant to use it at the workbench, not just read about the ideas in theory.
Little biographical information beyond his teaching role is easy to confirm from the sources I found. What does come through clearly is his interest in learning by doing, and that has helped keep his work alive for later readers interested in woodworking, education, and early twentieth-century craft instruction.
