Carleen Hutchins wasn’t formally trained in violinmaking, but despite that—or because of it—she changed the profession forever. With handfuls of Christmas glitter and a 150-year-old technique, she was able to visualize the vibrations of violin plates, allowing luthiers to rely to on the principles of acoustics instead of just “feel.” Traditionalists were outraged, but Carleen didn’t seem to mind. She had already spent most of her adult life pushing back on the constraints imposed on women in midcentury America. This episode explores Carleen’s life and legacy, the history of acoustics, the act of making sound visible, and our obsession with old Italian violins.
