For your convenience: a fresh, entirely re-typeset version of the "Clé de la Sténographie Duployé" (1900). Enjoy!
This is something I've wanted to do for years. Here it is at last, fresh and crisp.
So, why did I spend a few hours laboriously re-typesetting and redrawing the outlines of that "Key to Duployan Shorthand", published under various forms in French newspapers between 1894 and ~1910?
I can see several reasons to do it:
1° There are always people like me who will enjoy dabbling with a very simple shorthand whose entire theory fits on two A4 pages. Think of Orthic's popularity here! Sure, they won't reach ludicrous speeds (usually!), but the experience will be fun, and it might be perfectly adequate for things like journals, personal notes, etc.
2° As I mentioned a few times on this sub, Émile Duployé (1831-1912) was a pioneer in shorthand advertising, using posters, promotional postcards, and short summaries of his system in the national and local press. It is obvious that under the French Third Republic (1871-1940) Duployan became vastly more popular than other shorthands, way beyond the comparatively small circles of professional shorthand writers and typists.
Even today postcards written in Duployan can be found for a dime in garage sales, on sites like EBay or its local equivalents Le Bon Coin or Delcampe. It has become a small part of French popular culture of the late 19th and early 20th centuries, so it seems important to preserve this resource!
3° This Key to Duployan Shorthand is **remarkably** efficient and concise, I think. While the main Duployan textbook issued by Duployé is rather rambley, full of self-congratulatory speeches and embarrassingly bad poetry, the Key is clear and straightforward. French newspapers of that era were only 4-10 pages long. No room for bullshit! This is what Isaac Pitman understood when he published his Penny Plate in 1837.
Feel free to distribute this Key as much as you want! I added a watermark but I made it as unobtrusive as I could. Hope it will be useful to some of you!
