author
b. 1893
Best known as the co-author of a practical 1919 manual on woodturning, this early 20th-century writer helped turn workshop knowledge into clear instruction for students and beginners. Very little biographical detail is readily documented, which gives the surviving work an appealingly direct, hands-on character.

by Archie Seldon Milton, Otto K. Wohlers
Otto K. Wohlers is credited as the joint author of A Course in Wood Turning, published in Milwaukee by The Bruce Publishing Company in 1919 with Archie S. Milton. Library and public-domain records consistently identify him as Otto K. Wohlers, born 1893, and connect him with that instructional book on lathe work and woodworking.
The book itself suggests an educator's mindset: its preface explains that it grew out of problems given to high-school pupils and was arranged in a logical sequence, with an emphasis on proper tool use and steadily building skill. That practical, step-by-step approach has helped the work endure as a useful guide for readers interested in traditional woodturning.
Beyond that publication, reliable biographical information on Wohlers appears to be scarce in easily accessible sources. Rather than a large personal record, what remains most visible is the book itself—an accessible, workshop-based text from the early 1900s that reflects the teaching values and craft knowledge of its time.
