Samuel Zygmuntowicz (born 1956) is a contemporary luthier. He began his instrument making training when he was thirteen years old and studied making and restoration under Peter Prier, Carl Becker and René Morel.
Zygmuntowicz is the creative director of the Strad3D project, which The Strad Library called "One of the most groundbreaking and comprehensive studies of the violin form ever conceived." It involved the first ever 3D laser vibration scanning of Stradivari and Guarneri violins, and included acoustic testing and CT scanning. Zygmuntowicz turned the endeavor into a broad collaborative project including traditional documentation, musical performance, dendrochronology, and documentary film. The interactive DVD, which includes images and scientific research from the collaboration, was published and is available for purchase.
