Named after Lucien Gaudin, a French fencer (what other fame were you expecting?), who won two gold medals at the 1928 Olympic games. Likely a prohibition era cocktail due to the time of his fame, and based on the ingredients it would make sense.
From a quick search I am not sure how many of this Lucien Gaudin would have actually drank, his appearance is exactly what I think of for a creepy French guy, including some epic mustaches. The drink however, is a great looking cocktail and great flavor as well. A little less bitter and more citrus than a negroni, there is still a strong flavor to it, just more balanced than many Campari drinks.
Shake and strain into cocktail glass, garnish with an orange peel after first expressing the oils into the drink and onto the rim. Enjoy
