author
b. 1889
Best known for a practical early 20th-century book on preserving tomatoes, this little-documented writer appears in library and public-domain records rather than in the usual biographical sources. The surviving trail suggests a specialist author whose work was aimed at food processing and canning.

by W. G. (Wayland Gladstone) Hier
Wayland Gladstone Hier, usually listed as W. G. Hier, is an author attached to The Manufacture of Tomato Products, a 1919 work on tomato pulp, puree, catsup, chili sauce, soup, and related processing methods.
Available catalog and public-domain records consistently identify him as Wayland Gladstone Hier and give his birth year as 1889. Project Gutenberg lists him as the author of the book, and library records from HathiTrust and the Internet Archive match that identification.
Beyond those basic facts, reliable biographical details are scarce in the sources I could confirm during this search. I couldn't verify broader personal history, literary career information, or a trustworthy portrait image, so it is best to treat him as a lightly documented technical writer known primarily for this surviving food-manufacturing title.
