Klotz is a family of violin makers. Members of the Klotz (or Kloz) family have made violins in Mittenwald, Germany from the mid-17th century to the present. Dictionaries of violin makers list more than 25 artisans by this name.
Matthias I (1656–1743) founded the Mittenwald school of violin making after study with Jacob Stainer and Nicolo Amati. Typical labels:
Instruments by Sebastian I (1696–1768) are probably the most admired among the many existing examples by this family. Some instruments which have been identified as Sebastian's work bear his father's label. Typical labels:
Joseph (1743–1819), son of Sebastian, worked in a manner similar to that of his father.
The quality of their instruments varies enormously, and many inferior, unauthentic examples have labels bearing the Klotz name.
