b. 1850
Best known for practical books on punctuation, proofreading, and compound words, this late-19th-century language expert wrote for people who cared about clear, consistent English. His work grew out of real publishing and dictionary experience, which gives it a grounded, useful feel even now.

by F. Horace (Francis Horace) Teall
Born in Brooklyn on February 17, 1850, Francis Horace Teall built his career in the world of print. Biographical references describe him as starting in typesetting, and his own books present him as a critical proof-reader and editor connected with both the Century and Standard dictionaries.
Teall became known for reference-minded books about written English, including The Compounding of English Words, English Compound Words and Phrases, Punctuation, and Proof-reading. His writing focuses less on grand theory and more on the everyday decisions that matter to writers, editors, compositors, and proofreaders.
Other period sources also credit his work as an influence on style manuals and note his long association with The Inland Printer, where he edited the “Proof-room Notes and Queries” department. He died in 1923. No confirmed portrait image was located from the sources I could verify.
