The saxophone's 19th-century inventor, the Belgian Adolphe Sax, imagined hybrid horns that could combine the speed and fluency of woodwinds with the volume and punch of brass. Sax's career was almost derailed by a childhood of hair-raisingly frequent accident-proneness that led his mother to fear for his survival, but at 20 he patented a prototype contrabass clarinet, and then the first saxophone as its offspring.
