author
A 19th-century French naval officer, he wrote practical guides to ship rigging and maneuvering for sailors and students of seamanship. His surviving works are closely tied to hands-on maritime training rather than literary fame.

by Phocion-Aristide-Paulin Verdier
Phocion-Aristide-Paulin Verdier is known today for Nouveau manuel complet de marine, a French instructional work on seamanship that was published in two parts: one on gréement (rigging) and one on manoeuvres. Library and ebook records consistently credit him as the author of these works.
The available records also identify him as a capitaine de corvette, which places him in the world of the French navy. That fits the character of his writing: clear, practical material focused on how ships were equipped, handled, and worked at sea.
Very little biographical detail appears to be easily confirmed online beyond his authorship and naval rank. No reliable portrait was found from the sources checked, so it is best to treat him as a somewhat obscure technical author whose reputation rests mainly on this maritime manual.
