author
An early 20th-century forestry student and technical writer, he is best known for a practical look at how motor trucks were changing the logging industry. His surviving work feels clear-eyed and hands-on, capturing a moment when new machinery was reshaping work in the woods.

by Frederick Malcolm Knapp
Frederick Malcolm Knapp is known for Motor Truck Logging Methods, published in 1921 by the University of Washington's Engineering Experiment Station. The book presents a detailed, practical study of truck-based logging, including equipment, road construction, hauling methods, and operating costs.
The publication identifies him as a student in the College of Forestry at the University of Washington, which helps place him in the world he was writing about: close to both forestry education and the fast-changing logging trade of the Pacific Northwest. His writing is notably direct and technical, aimed at explaining how motor transport could be used effectively in logging operations.
Very little biographical information appears to be readily available beyond this work, so most modern readers encounter him through that book rather than through a well-documented personal history. Even so, the surviving text offers a useful snapshot of industrial forestry at a time of transition from older hauling methods to motorized logging.
