Duployan Letter D

It began as shorthand for writing French quickly.

Duployé learned an earlier French shorthand tradition shaped by Taylor-Bertin and Aimé Paris. A guide to his shorthand appeared in 1860; the distinct method bearing his name followed in 1867. In British Columbia, Catholic missionary Jean-Marie Le Jeune expanded Duployan into Chinuk Pipa (Chinook writing), used for Chinook Jargon and local Indigenous languages. The mission newspaper Kamloops Wawa carried it from 1891–1923, and readers also wrote letters in it.
