Rene Voisin was born in 1893 and died in 1952. His father, Georges Gabriel Voisin, was born in 1871 and was a painter and glazier and had a flourishing family business in Angers, France. Georges devoted his leisure time to his passion for music, even founding with his own money the "Angers-Doutre Wind Band" pictured below. His only son, Rene took lessons from his father and Georges was so good at teaching that Rene went off to Paris to study at the Paris Conservatory. The rest, as you say, is history.
As I continue to sift through the Voisin Family archives, I will be adding content on my grandfather. For now, here are some pictures to get you started.
