author
A practical late-19th-century writer on steam power, this author is best known for a clear, hands-on guide aimed at young engineers learning to run and care for engines and boilers. The work feels grounded in real shop-floor experience rather than theory alone.

Little biographical information about this author is easy to confirm, but Young Engineer's Guide was published in the 1890s and is associated with Racine, Wisconsin.
In the book's own prefatory material, the author explains that the manual grew out of collected practical notes on the care and operation of steam engines and boilers. He also says he had been employed for years by the J. I. Case Threshing Machine Company, which helps explain the book's direct, experience-based tone.
That background makes the work especially useful as a period guide for readers interested in mechanical practice, agricultural engines, and the everyday knowledge expected of young engineers at the end of the 19th century.
