Lorn Campbell

Published evidence located during this search points to Lorn Campbell as the author of Oxy-acetylene welding manual, first issued in 1919 by John Wiley & Sons. The surviving catalog records suggest he wrote practical instructional material rather than literary fiction, and that this book is the work most clearly tied to his name.

Reliable biographical detail about his wider life is scarce in the sources found here. A general-reference biography page lists him with the dates 1891–1955, but stronger, more detailed library or archival sources located in this search did not provide a fuller life story, so it is best to treat him as a somewhat obscure figure whose published legacy rests mainly on technical writing.

No confirmed portrait image for this author was found from the pages checked during this search.
