W. N. (William N.) Cornett
Best known for practical early-20th-century language manuals, this writer focused on helping readers use Spanish in real conversations and business settings. The surviving record is thin, but the books themselves suggest a teacher interested in clear, useful communication rather than theory alone.

Hossfeld's Spanish Dialogues, and Idiomatic Phrases Indispensible for a Rapid Acquisition of the Spanish Language
by W. N. (William N.) Cornett, C. Hossfeld
About the author
W. N. Cornett, also listed as William N. Cornett, is known today through a small group of language-learning and commercial correspondence books. Project Gutenberg credits him for Hossfeld's Spanish Dialogues, and Idiomatic Phrases Indispensible for a Rapid Acquisition of the Spanish Language, and bookseller records also connect his name with Spanish Commercial Correspondence and Technicalities, Etc. along with similar practical guides.
His work appears to belong to the early 1900s, when self-instruction manuals and business language handbooks were especially popular. Rather than writing fiction or memoir, he seems to have specialized in tools for learners who wanted usable Spanish for travel, conversation, or trade.
Very little confirmed biographical information about his life has surfaced in the sources I found, so it is safest to remember him through his published work: concise instructional books meant to make language study more direct and practical.
