Charles N. (Charles Newton) Pickworth

Born in 1861 and active in Britain’s engineering world, Charles Newton Pickworth built his career through workshop experience before moving into technical journalism. Sources describe him as a mechanical engineer who worked for Mechanical World, first as an assistant editor from 1889 and then as editor from 1891.

He became well known for writing straightforward engineering handbooks rather than abstract theory. His best-known book, The Slide Rule: A Practical Manual, was especially influential and was issued in many editions, helping generations of readers learn a key calculating tool of pre-digital engineering. Other works associated with him include Logarithms for Beginners and The Indicator Handbook.

Pickworth died in 1955. Today he is remembered less as a literary figure than as a gifted explainer: an author who turned the everyday instruments of engineering into books that working readers could actually use.
