Music boxes were also hidden within table-top snuff containers inlaid with gold, pearls, and ivory. The key to the music boxes' portability was a tuned steel comb, invented in 1796 by Antoine Favre in Switzerland’s clock-making region, La Vallée de Joux. The first steel combs were made from varying lengths of metal arranged in a curving fan-shape. As the pins on a rotating cylinder struck the teeth of the comb, notes were produced. Much like early musical clocks, these machines were spring-wound. In 1810, David LeCoultre, of the famous LeCoultre watch-making family, designed a brass cylinder to play notes on a straight length of tuned steel teeth. Longer cylinders could be pinned for multiple tunes and adjusted laterally to switch between songs. A few years later, Francois Nicole, of the famous Nicole Frères firm, created a steel hairspring damper to soften the ring of each note, and the modern music box was born. However, it wasn’t until 1875 that the first music box factory was opened by the Paillard company in St. Croix, Switzerland. Previously, all music boxes were produced through smaller cottage-industry operations using the skills of different craftspeople to assemble a complete product.
