'Saxophone' is 'Sax's sound' — named after Belgian inventor Adolphe Sax plus Greek 'phone' (sound).
A metal wind instrument with a single-reed mouthpiece, used especially in jazz and dance music.
A modern eponym: from the inventor's name Adolphe Sax (1814–1894), a Belgian instrument maker, combined with Greek 'phōnē' (voice, sound), from PIE *bʰeh₂- (to speak, to say, to shine). Sax patented the saxophone in Paris in 1846, combining a single-reed mouthpiece (like a clarinet) with a conical metal body (like an oboe) to create an instrument that bridged the power of brass with the agility of woodwind. He deliberately named it after himself — a then-unusual practice that succeeded commercially where his other inventions (the saxhorn, saxotromba, saxtuba) fared less well. PIE
Adolphe Sax survived an extraordinary number of near-death experiences as a child: he fell from a three-story building, swallowed a needle, drank a bowl of acidic water, fell onto a hot cast-iron pan, and was nearly suffocated by varnish fumes. His neighbors called him 'the ghost child' because they kept expecting him to die.
