Piero Badalassi (1915–1991) was a Pisa-based Italian maker, widely linked to the Tuscan school and influenced by Igino Sderci. His work shows tidy, classical modeling with medium arching, crisp purfling, slender f-holes, and orange-gold varnish. Known for clean workmanship and poised, projecting tone—his violas are especially admired.
