author
b. 1893
Best known as the co-author of a practical 1919 guide to woodturning, this early 20th-century writer helped shape a hands-on, classroom-friendly introduction to the craft. His surviving record is slim, which gives his work an old workshop feel that still comes through today.

by Archie Seldon Milton, Otto K. Wohlers
Otto K. Wohlers is a little-known early 20th-century author remembered primarily for A Course in Wood Turning (1919), written with Archie S. Milton. Library and catalog records consistently identify him as being born in 1893 and credit him as a joint author of the book.
The book was published by The Bruce Publishing Company in Milwaukee and was designed as a structured introduction to woodturning. In its own prefatory material, the work presents itself as growing out of problems given to high school pupils, which suggests a practical, teaching-oriented approach rather than a purely theoretical one.
Beyond that collaboration, reliable biographical details about Wohlers are hard to confirm from the sources available here. Even so, his name remains attached to a durable manual that has stayed in circulation through library archives, Project Gutenberg, and later reprints, giving him a modest but lasting place in woodworking literature.
