Cesare Maestri, born October 2, 1929 in Trento and died January 19, 2021 in Tione di Trento in Trentino-Alto Adige, was a contemporary Italian mountaineer and writer. Cesare Maestri first studied theater and art history in Rome but returned to Trento to work as a guide and ski instructor. It begins to climb in the Brenta massif and then opens many routes, often solo, in this massif and in the Dolomites. Maestri was quickly nicknamed “the Spider of the Dolomites” (in Italian: Il Ragno delle Dolomiti).
