Tourte was the most renowned bowmaker of the eighteenth century, recognized as the first to experiment with pernambuco wood. as the public became aware that of all of the varieties of pernambuco wood that exist in different regions and countries of the world, only those varieties native to the country of Brazil in the Atlantic Forest are the best for bows.
Europeans thus came to know Horst John in the twentieth century as one of the most important suppliers of pernambuco wood and they came to recognize his pioneering studies of the fine raw material, even adopting John’s classification system to facilitate the selection of the most important varieties of pernambuco wood to be used in bowmaking.
John created five categories of the native Brazilian pernambuco wood based on criteria including soil, environment, color, texture, veins, grain, density, elasticity, weight. These categories are: Peccatte, Sartori, Dodd, John (Vermelho) Red, and
John (Amarello) Yellow.

John’s classification system aided the separation of the wood for stacking by instrument. He perfected the naturally dried process and produced standards of quality in acclimatization.
