Researching the Prager dynasty of violin and bow makers reveals numerous family members with various (and sometimes conflicting) forenames and birth and death dates. Luthiers named Prager can be traced back to the early 19th century in Markneukirchen, Germany, including violin maker Wilhelm Heinrich Prager and bow maker Friedrich Wilhelm Prager (presumably relatives), who worked in Landwüst—a region of Markneukirchen—in the early 1800s. Friedrich Wilhelm's sons, Gustav Oskar (also possibly known as Gustav Adolf and Oskar Gustav) Prager (1866–1953) and August Edwin Prager (b. 1875), developed the outstanding reputation of the family name with their training in Leipzig at the workshop of Ludwig Bausch (known as the "German Tourte") and their successful businesses established in Markneukirchen. The Prager brothers' bows were widely admired and copied—numerous German bows were branded with the Prager name and exported during the prolific period of violin and bow production in Germany at the turn of the 20th century. We believe this bow to be an authentic Gustav Prager cello bow, representing the best of what the family produced.
