Trained as a violinist, he made his first violin on his own and received praise for it. Thus he decided to become a violin maker and moved to Milan to work with the Antoniazzi family in 1886. With them he established a partnership of exceptional importance, putting to good use his artistic skills and business ability. After having moved his workshop to various premises, he retired to his villa in Venegono leaving his sons Andrea and
Carlo Bisiach to continue the business in Milan. Bisiach was a prominent figure in the commerce of antique violins. He trained a number of luthiers, including Gaetano Sgarabotto, Igino Sderci, Pietro Borghi, Ornati and Garimberti. His workshop can be considered the most important in Italy in that period. The following instrument makers worked at Bisiach's:
Riccardo Antoniazzi,
Romeo Antoniazzi,
Gaetano Sgarabotto,
Giuseppe Ornati,
Ferdinando Garimberti,
Igino Sderci,
Rocchi Sesto, Carlo Carletti, Cipriano Briani, Camillo Mandelli, Ferriccio Varagnolo, Camillo Colombo, Vincenzo Cavani, Pietro Paravicini, Albert Moglie, Andrea Bisiach,
Carlo Bisiach, Pietro Borghi, Mirco Tarasconi, Leandro Jr. &
Giacomo Bisiach, Iginio Siega and Carlo Ferrario. With the death of the last of the great Cremonese masters towards the end of the 18th century, only the Cerutis remained in
Cremona. It was the Antoniazzis who undertook the task of transferring the scant knowledge saved from oblivion from Cremona to Milan. Leandro Bisiach did a great deal of research and found some old recipes, which he used to create antiqued varnishes for the numerous copies he made. He primarily used a varnish of a light red-orange color although it varied greatly from one instrument to another. To give an instrument an aged look he very often shaded off the varnish only at the base of the back plate. Bisiach used a large number of diverse models but principally those of
Stradivari, Amatise and other models of
Guarneri,
Balestrieri,
Guadagnini,
Gagliano,
Enrico and
Giovanni Battista Ceruti or other violin makers from Veneto in the 18th century. He also utilized many others as chance would have it. Bisiach received various awards and recognition from exhibitions at Atlanta 1895-1896,
Turin 1898,
Paris 1900, Milan 1906 and
Brussels 1910. "The shaping of the back, in Bisiach's instruments, can be identified by the accentuated hollowing out that emphasizes the border, which is rounded. The inlay has a large central white strip and two very narrow black threads, short and slightly closed corners, an echo of the Stradivarian style. The F holes are cleanly and precisely cut, while the columns of the ribs are clearly inspired by the classic Cremonese school. Bisiach's varnishes, usually a beautiful red-brown, have brilliant yellow-gold reflections." - Pardo Fornaciari, Arte Liuteria Musicians who owned Leandro's instruments included American violinists Sebastian Campesi and
Nathan Milstein. == Quotes ==
