Career
Bosret was blinded at the age of seven due to an accident, but this did not stop him from receiving a musical education: he was taught by the organist of the Saint Loup church (Namur). He stayed at this church, earning a living as an organist and a teacher of solfège. In 1851 he composed Li Bia Bouquet (originally named Li bouquet del marieye), a song in the Walloon language that gained a lot of popularity in that city and became the official hymn of the city in 1857.
