J. V. Rohan

Very little confirmed biographical information about this author appears to survive in the major public sources available online. J. V. Rohan is chiefly known today as the author of Young Engineer's Guide, a late 19th-century manual that has been preserved by Project Gutenberg and library archives.

The book was published in 1894 and is aimed at young engineers and beginners working with steam engines and boilers. In its opening material, the author presents the book as a practical digest of mechanical information, shaped by direct experience and by attention to the everyday questions asked by working engineers.

That surviving work suggests a writer less interested in theory for its own sake than in useful instruction: operation, maintenance, safety, and efficiency. Even with so little personal detail available, the book has lasting value as a window into the world of steam power and technical education in its era.
