The largest of the great Mirecourt instrument making firms. Jérôme Thibouville-Lamy, or J.T.L. for short, came about from the merger of several prominent French workshops. Jérôme Thibouville came from a family of well established makers of instruments. Teaming up with Husson-Buthod they formed Husson-Buthod-Thibouville. They adopted the name Jérôme Thibouville-Lamy following the marriage of Jérôme Thibouville and Marguerite Hyacinthe Lamy, a cousin of his business partners. The company peaked at an annual production of 150,000 instruments produced by more than 1,000 luthiers. JTL employed many excellent luthiers, combining generations worth of technical knowledge under one company, allowing them to produce some of the finest French violins of their time which are now much sought after.
