Andre Levi was an Italian engineer, as well as a passionate classical music and violin lover who chose in his early 30s to turn his live around and follow his real call. Self-taught, he established himself as violin maker in France in the 70s and developped a method of tone enhancement based on its research in acoustics. He started sharing with musicians the (at the time) unsung treasure of modern Italian violin making.Imposing himself as the leading expert on those late nineteenth and early twentieth instruments, it was in the mid-80s that he transfered his workshop to #48 of the famous Paris's street of Rome; right within the ancient walls of the 'Charles Enel's violin workshop", founded in 1911.

Frédéric Levi spent his childhood and part of his youth amid violins and varnish scents, accompanying several months a year his father André visiting other maker workshops across Italy. After scientific studies in France, he studied violin making in Newark (UK) and perfected restorations techniques in many workshops such as Gosling (UK), Morel (NY, USA), Schmitt (Lyon). In 1999 he officially took over the family's workshop, succeeding his father for the expertise. In the early 2010s, he designed and licensed "CertiQR", an unprecedented online authentification for the bow certificates from the Cabinet d'Archetiers Experts Jean François Raffin. Through the time spent with J F Raffin, Sylvain Bigot and Yannick Le Canu, he expanded his interest in the expertise of bows and collaborated with them to the creation of reference publications.
