Giuseppe Ruggieri, also known as Giuseppe Guarneri 'filius Andreae' (son of Andrea), was an Italian luthier from the famous Guarneri family of violin makers, which played a significant role in the development of the craft in Cremona, Italy, during the 17th and 18th centuries. Born in 1691, Giuseppe was the son of Andrea Guarneri, who was a pupil of the renowned luthier Niccolò Amati and the founder of the family workshop. Giuseppe was thus born into an environment steeped in the tradition of violin making, which would have a profound influence on his own career as a luthier.
Giuseppe Ruggieri worked closely with his father and inherited the family workshop after his father's death. His work is often overshadowed by that of his more famous relative, Giuseppe Guarneri 'del Gesù', whose instruments are ranked alongside those of Antonio Stradivari for their quality and sound. Despite this, Giuseppe Ruggieri's violins, violas, and cellos are still respected for their workmanship and tone, although they are not as frequently encountered on the current market.
Ruggieri's style evolved over the course of his career. His early instruments often feature a deep, warm varnish and a robust construction, while his later works demonstrate a more refined approach, with attention to detail and a lighter application of varnish. Throughout his career, Ruggieri showed a consistent interest in experimenting with the model and size of his instruments, which contributed to the variety and individual character found among his surviving works.
Giuseppe Ruggieri continued to build instruments until his death in 1743. His contribution to the field of luthiery helped to sustain the reputation of the Cremonese school of violin making during a period when the dominance of the Amati and Stradivari workshops could have eclipsed other talented makers. Today, instruments crafted by Ruggieri are held in high esteem by musicians and collectors, and they serve as a testament to the enduring legacy of the Guarneri family's craftsmanship.
