Our Legacy

The Hans Weisshaar Story

Hans Weisshaar

Hans Weisshaar, Master Violin Maker, arrived in the United States in 1937 after studying at the famous German State School for Violin Making in Mittenwald and working in Switzerland, Holland, and Germany.  He became an American citizen and during those early years, worked for William Lewis and Son in Chicago, then for Emil Hermann in New York.  In Hermann’s well-known shop, Weisshaar worked alongside the maker who would become the most influential violin restorer of the 20th century, Simone F. Sacconi.

In New York, Weisshaar met the violin virtuoso Nathan Milstein, who urged Weisshaar to go west to Los Angeles, where there had been a dire need for a professional violin maker and restorer.  So in 1947, he moved to Los Angeles and established the first world-class violin making and restoration workshop in the western United States.

With his reputation for high standards, Weisshaar’s firm became the destination of an ever-expanding constellation of luminaries, including Pablo Casals, Mischa Elman, Zino Francescatti, Jascha Heifetz, Yehudi Menuhin, Michael Rabin, Isaac Stern, Heinryk Szeryng, and Joseph Szigeti, and Alice and Eleonore Schoenfeld.

Hans Weisshaar maintained one of the largest professional violin and bow making and restoration workshops in the United States and he became a mentor to scores of young violin and bow makers and restorers from around the world in his atelier.  Mr. Weisshaar made history with his unprecedented restorations of the “Red Diamond” violin, which afterward became dramatic international news, and “The Bass of Spain” cello, both made by Antonius Stradivari.

As a driving force in the violin trade, Mr. Weisshaar was a co-founder of the American Federation of Violin and Bow Makers in 1980.  The Manual for Violin Restoration, co-authored by Hans Weisshaar and Margaret Shipman, was a milestone for the company and the violin making trade. Mr. Weisshaar lived to see its publication in 1988 and enjoyed its many accolades. Upon his death in 1991, Ms. Shipman took over the firm.

Georg Eittinger, Master Violin Maker, was mentored in the Weisshaar workshops.  He bought the company in 2004 and opened a branch of the Weisshaar company in Berlin in 2005.

Georg Eittinger

Georg Eittinger, Master Violin Maker, has spent 30 years in the violin trade and is respected for his expertise and unique talent in restoration and conservation of rare antique violins, violas, cellos, and bows. A graduate of the German State School of Violin Making in Mittenwald, Eittinger holds the German Master Craftsman Diploma (Geigenbaumeisterbrief) and has held senior positions in important violin restoration departments in London and Munich. In addition, he builds new instruments on commission, particularly replicas of rare Italian stringed-instruments.

Previously employed in the London firm of J&A Beare, Mr. Eittinger has been the owner and President of Hans Weisshaar since 2004. He provides his expert opinion on rare and important string instruments and bows to a worldwide clientele of professional musicians, collectors, foundations, and other investors and institutions.  In 2005, he opened a branch of Hans Weisshaar in Berlin.

Eittinger oversees trained violin makers, who continue to come to Los Angeles to expand their knowledge of fine instrument restoration. Mr. Eittinger also teaches the bi-annual Weisshaar Restoration Course for professional violin makers at the German State Violin Making School in Mittenwald, Germany and in Cremona.  He lectures and writes articles on the art of violin making, restoration, and the violin trade.

IN 2016, Georg Eittinger opened a second location of Hans Weisshaar in the Los Angeles area in the scenic and historic city of San Marino, home to the Huntington Library and Botanical Gardens. This location quickly became popular with our clientele.

Since the summer of 2018, the location at Huntington Blvd. in San Marino has become the primary and only location in the Los Angeles area, opening a new chapter of offering outstanding instruments, and service and expertise in the violin business and field of the violin making and restoration.

The field of fine bowed instrument restoration has evolved into an art within the craft of violin making. Refinement in restoration techniques has paralleled the increase in value of antique instruments during the last few decades. There has been a shift from the mere replacement of damaged parts in an instrument, done in past centuries, to today’s meticulous and painstaking preservation and conservation of original materials.

Only highly-skilled and experienced restorers can meet the changing demands in this specialized field and achieve the result which both players and important instruments deserve. Instrument restoration requires a thorough understanding of the concepts of violin making throughout history and knowledge of the instrument making centers in Italy, France, England and Germany.

Preserving the originality of an instrument or bow as an individual work of art is the foundation of the expert treatment in the Hans Weisshaar restoration department. We consider the demands of today’s performers as well as the cultural importance appreciated by collectors.

Many of the techniques, tools and materials used at Hans Weisshaar are the same ones used in fine art restoration and in the medical field. Our workshop is able to restore instruments to their former glory due to proper application of modern technologies, which are far less invasive to the original instrument.


During the lifetime of a bow or an instrument, each undergoes routine procedures, from frequent cleaning or the rehairing of bows to sound adjustments and complicated accident repairs of instruments. Long-term restorations, which can sometimes last even years, require specialized care and expertise.

The Hans Weisshaar firm offers all services necessary for the string musician, for full-size and smaller instruments and for every level of ability. These include bow rehairing and adjustments for playability and sound. We help choose the right set of strings and advise you about useful accessories: a variety of fine tuners, bridges, pegs, chin and shoulder rests and our genuine Weisshaar cello endpins.

Hans Weisshaar is acquainted with all the major musical instrument insurers, and has dealt with them on a regular basis for decades. We gladly assist our clients in cases of claims or accidents.
