Igino (Iginius) Sderci (1884 - 1983, born in Gaiole in Chianti, Italy) was a violin maker who studied under master maker Leandro Bisiach. 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). From his earliest childhood Igino Sderci was interested in music and art. He studied sculpture in Siena and had a gift for wood carving. He made his first violin without supervision. In 1917 Sderci was introduced to Leandro Bisiach by Don Fortunato (Sderci's brother) and Count Guido Chigi-Saracini in Siena. To Sderci’s good fortune, he did not serve in the war owing to circulatory problems in his legs, a lifelong condition. Sderci had worked as a sculptor & carver for his uncles Tito and Giuseppe Corsini in Siena making richly decorated furniture, and then in a factory making ladies’ shoes, even designing some with removable heels. Recognizing his innate talent and needing an assistant, Sderci was taken on by Leandro Bisiach. At the end of the war, when Carlo Bisiach joined his family in Siena, Igino was put under Carlo’s guidance for training. Sderci excelled quickly as he was ardent about violin making. Newly found archival evidence (from Milan and Siena as well as De Paolis family) shows that “Sderci worked with Bisiachs mainly in Siena, and the only recorded time he visited Milan was for the wedding of Bisiach’s daughter Amina to Lorenzo De Paolis (famous cellist) in 1921 at their villa in Venegono Superiore, near Milan.” The Historical Archive of Siena points out that “Igino Sderci emigrated to Florence on August 14, 1926” (not earlier). Hence Igino’s early instrument Amatese Strad was labeled ‘fecit in SIENA Anno 1924’. Igino Sderci became an important figure to have come out of the Bisiach workshop. After leaving Leandro’s shop, he continued his collaboration with Bisiachs making instruments in the white for Giacomo and Leandro Jr., models of Camillo Camilli, Pietro Guarneri di Mantua, Stradivari 1732 Ex Busch and Amatise Stradivari. While for Carlo Bisiach he used G.B. Guadagnini, Amatise Stradivari and Stradivari 1709 models. He also made instruments in the white for Simone Ferdinando Sacconi. Igino Sderci copied many models and created new designs and reflected their influence as his instruments are full of character and made with utmost care. Without exception he used
