Giovanni Battista Giusti

Giovanni Battista Giusti (ca. 1624, Lucca, Tuscany — ca. 1693), or "Joannes Baptista Justi," was an Italian harpsichord maker. Only scarce historiographical sources exist, including a church registry listing "Joannes Baptista, son of the late Antonio Justi of Lucca" uncovered in 1989 by Italian musicologist Patrizio Barbieri. Between 1648 and 1664, he apprenticed with a renowned master Giuseppe Boni 'il Cortona' (ca. 1629—1702), subsequently working under Girolamo Zenti (ca. 1609—ca. 1666), before Giusti opened his atelier in Lucca, active between 1676 and 1693. According to other sources, Giovanni worked in Rome.

Around 12 to 20 extant instruments are currently attributed to Giusti, with at least half generally regarded as counterfeit; particularly, an infamous Italian antique dealer and fraudster, Leopoldo Franciolini (1844—1920), produced many blatant "Giusti" fakes.
