1846–1901
Best known for practical school and reference books, this late-19th-century writer focused on making punctuation and civics clear, useful, and easy to teach. His work reflects a teacher’s habit of turning complicated rules into plain guidance.

by William Johnson Cocker
William Johnson Cocker was an American author active in the late 1800s, remembered for educational and reference works rather than for fiction. His books include Hand-book of Punctuation, The Government of the United States, and The Civil Government of Michigan, which suggests a strong interest in both clear writing and public instruction.
His published work points to a practical, classroom-minded style. Instead of writing for literary fame, he appears to have written books that helped students and general readers understand punctuation, capitalization, letter-writing, proof-reading, and the basics of government.
The dates 1846–1901 are commonly associated with him in library and archival records. I wasn’t able to confirm many personal details beyond his authorship and published works from reliable readily available sources, so this overview stays focused on the books that can be verified.
