When I attended Gary Regan's Cocktails in the Country retreat in 2015, I had my turn making drinks for everyone during the Organized Chaos session. In my 20 minute time block, I came up with 5 or 6 drinks on the spot with this one being my favorite, and it started by spying the bottle of Camus Cognac on the shelf. The direction I took was inspired by the Lucien Gaudin for I paired Campari with curaçao. In the Negroni-variation vein, I also thought of Phil Ward's 2005 Cocktails in the Country drink, the Cornwall Negroni that had Punt e Mes and bitters in the mix. For a name, I stuck with the Lucien Gaudin concept and dubbed this one after another fencer, Rene Barbier -- a Frenchman who medalled in the 1928 Olympics. I did not take down tasting notes during the melee, but I do recall Gaz commenting that "this is my sort of drink!"
