A crystalline substance (Rochelle salt) used in chemical experiments and electronics, named after La Rochelle, France, where it was first produced.
Named after La Rochelle (meaning 'the little rock' in French), a port city on the Atlantic coast of France. The salt was first commercially produced there in the 17th century by apothecaries.
Rochelle salt was revolutionary in early electronics—it's a piezoelectric crystal, meaning it creates electricity when squeezed and vibrates when electricity is applied, which made it essential for early radio and phonograph technologies before synthetic alternatives were developed.
Rochelle became feminine-coded in English during the 19th century, though the French origin (from 'roche,' meaning rock) is gender-neutral. Modern perception defaults to female.
Use as a proper name per individual preference; avoid gendered assumptions in documentation.
Rochelles have contributed significantly in science, law, and the arts; respect the individual identity.
