author
A practical early-20th-century writer on steam engineering, best known for turning boiler-room know-how into a clear question-and-answer guide for working stokers. The surviving record is thin, but the book itself shows a hands-on teacher focused on safety, efficiency, and everyday skill.

by W. J. Connor
Very little biographical information about W. J. Connor could be confirmed from the sources available during this search. Connor is known as the author of The Stoker's Catechism, a concise instructional work on steam boilers and the work of stokers.
The book was published in 1906 and was aimed at helping readers learn boiler operation, firing methods, and related practical duties in a straightforward question-and-answer format. Its tone suggests an author with direct working knowledge of engine-room practice and an interest in making technical instruction useful to beginners as well as experienced workers.
Because reliable personal details such as full name, dates, or a fuller life history were not clearly available in the sources reviewed, this overview focuses on the work that can be confirmed rather than speculating beyond the record.
