Making more than 700 instruments including many large violas, he won gold medals at the prestigious Stradivarius Exhibition at Cremona in 1937 marking the bicentenary of Stradivari's death (as well as prizes in 1949).

However the most important event for the renaissance of violin-making in Lombardy was certainly the meeting between Riccardo Antoniazzi and Leandro Bisiach; the latter, thanks to his talent, his taste and his business ability succeeded in founding, at the end of the 19th century, a workshop which soon gained international fame.
Bisiach was an outstanding figure in the commerce of antique violins but above all had the merit of raising a generation of great luthiers, among whom for example Sderci, Pietro Borghi, Giuseppe Ornati and Ferdinando Garimberti come to mind."
