K. A. (Kristian A.) Juthe
Best known as the co-author of an early practical guide to steelworking, this little-documented writer helped explain annealing, heat treating, and hardening in clear, applied terms. His surviving record is sparse, which gives his work an appealing sense of hidden industrial history.

The Working of Steel Annealing, Heat Treating and Hardening of Carbon and Alloy Steel
by Fred H. (Fred Herbert) Colvin, K. A. (Kristian A.) Juthe
About the author
K. A. Juthe, identified in library and public-domain records as Kristian A. Juthe, is known chiefly as the joint author of The Working of Steel, published with engineer and technical writer Fred H. Colvin in 1922. The book focuses on annealing, heat treating, and hardening carbon and alloy steel, and it has remained accessible through library catalogs and Project Gutenberg.
Beyond that publication, reliable biographical information about Juthe is limited. Some genealogy-style sources list a Kristian Juthe born in 1871 and dying in 1967, but without stronger confirmation it is safest to treat that as possible rather than certain.
What stands out most is the book itself: a practical, experience-based work from the early twentieth century, written for readers interested in how steel behaved in real industrial settings. For audiobook listeners and history-minded readers, Juthe's name survives through that useful collaboration and the window it opens onto the working world of metallurgy.
