[1] Du Locle was responsible for completing the libretto of Giuseppe Verdi's Don Carlos (1867) after the death of Joseph Méry.
[2] According to Charles Pigot, Du Locle inspired the subject, words and music of Bizet's Djamileh (1872).
[4] In 1876, a financial dispute arose with Verdi,[5] and Du Locle moved to Capri, where he constructed and lived in the Villa Certosella, now a hotel.
One day he started attracting attention by wearing a suit and cape made of rough, uncoloured wool, a fabric usually only worn by fishermen.
Soon many of the Germans and English on the island adopted attire made of similar material, which stimulated a local industry of hand-woven wool cloth which persisted until machine-made fabrics took over several decades later.
