Horst L. Kloss, Mittenwald-trained Master Violin Maker, has worked with fine stringed instruments and bows for over four decades. In 1970, he established Kloss Violins, the oldest professional violin shop in New England, where he specializes in violin making (using the golden proportions to design instruments. He also specializes in acoustic adjustment, custom instrument set-up, and the repair, restoration, and appraisal of historic instruments and bows. His formal training was at the State Bavarian School of Violin Making in Germany, where he earned his Journeyman’s diploma in 1964 and his Master’s Degree in 1972. He also had the privilege of training under the tutelage of Bruno Paulus from 1964 until 1965 while he was in Germany, and then under the guidance of Carl Becker (Sr. and Jr.) when he came to the U.S. to work at William Lewis & Sons in Chicago. He is one of fewer than 100 violin makers whose training and skills qualify him for full membership status in the Amer. Fed. of Violin and Bow Makers. And he was selected from a handful of Federation members to take part in an intensive training at the Smithsonian on varnish restoration and conservation. He has cared for collections of note, including the Boston Museum of Fine Arts’ historic stringed instruments. Mr. Kloss taught violin repair and restoration and violin building at UNH’s Violin Institute from 1996 to 2017.
