J. V. Rohan
Best known for Young Engineer's Guide, this late-19th-century writer offered practical, plainspoken advice for people learning to run and maintain steam engines. Even though little biographical detail seems to survive, the book still gives a clear sense of a hands-on teacher who wanted engineering knowledge to be useful.

Young Engineer's Guide
by J. V. Rohan
About the author
J. V. Rohan is a little-documented American technical writer associated with Racine, Wisconsin. The clearest surviving record found here is Young Engineer's Guide, a practical manual on steam engines and boilers that identifies him on the title page as being from Racine and carries a copyright date of 1894.
Library and public-domain records show that Young Engineer's Guide was published in multiple editions, including 1894 and 1899, and it has remained available through modern library catalogs and Project Gutenberg. The book is aimed at young or less-experienced engineers and focuses on operation, maintenance, troubleshooting, and workshop know-how rather than theory alone.
Because reliable biographical sources are scarce, it is hard to say much more with confidence about the person behind the initials. What can be said is that the surviving work points to an author deeply engaged with the steam technology of the era and interested in making complicated machinery understandable to working readers.
