author
b. 1880
A practical writer from the early 1900s, best known for explaining paper-box making in clear, hands-on detail. His work speaks to a time when craft, printing, and small-scale manufacturing were closely connected.

by Robert F. Salade
Little biographical information about this author could be confirmed from the sources I found. He is credited as Robert F. Salade or Robert Francis Salade and is associated with the instructional book How Paper Boxes Are Made.
That book is a practical manual for beginners, covering the making of many kinds of paper boxes and related shop work such as printing, embossing, gold-leafing, label work, and watercolor box manufacture. Based on the surviving records available online, his published work appears to be rooted in industrial craft and vocational instruction rather than literary writing.
Because reliable personal details were scarce, it is safest to remember him as a specialist author whose work preserved everyday manufacturing knowledge from an earlier era.
