François Xavier Tourte (1747 - 1835) was a Frenchman who, though trained as a watchmaker, soon changed to making bows for playing classical string instruments such as the violin.
He has often been called the Stradivari of the bow. .
He made a number of significant contributions to the development of the bow, and is considered to be the most important figure in the development of the modern bow.
Tourte's bows are made from pernambuco wood, the most usual form of wood used on professional bows today, bent by being exposed to heat. Tourte's bows tended to be heavier than previous models, with more wood at the tip of the bow counterbalanced by a heavier frog (the device connecting the hair to the stick at the end nearest the player's hand).
They generally have a usable hair-length of around 65cm, and the balance point is 19cm from the frog. The bows were elegantly fluted through half, or sometimes the whole, of their length. The curve in the wood was created by heating the wood thoroughly and then bending it. Before Tourte, bows had been cut to the desired bend. The final important change credited to Tourte is the screw in the nut to moderate the tension in the hair. This propelling and withdrawing screw is found on virtually all modern violin bows.
This new design was approved of by Louis Spohr who described Tourte's bows as having "trifling weight with sufficient elasticity of stick and the beautiful and uniform bending, by which the nearest approach to the hair is exactly in the middle between the head and the frog". He praised Tourte's "extremely accurate and neat workmanship".
At the height of his career, a single Tourte bow fetched 15 Louis d'Or. Tourte destroyed any bow that was not entirely faultless before it left his workshop. He never varnished his bows but only rubbed them with pumice powder and oil. The Tourte pattern was followed by Dominique Peccatte, Nicolas Eury, Nicolas Maire, Francois Lupot, Nicolas Maline, Joseph Henry and Jean Pierre Marie Persois.
"Tourte - French family of bowmakers and luthiers. It comprised of Nicolas Pierre Tourte and his sons Nicolas Léonard and François Xavier and perhaps Charles Tourte, son of Nicolas Léonard. In addition, at least two channelled (canalé) bows dating from about 1750–60 exist bearing the brand-stamp A.TOURTE." - Paul Childs
