The Duke of Alcantara Stradivarius is a violin made by Antonio Stradivari of Cremona, Italy in 1732. In 1929 it was purchased by a collector in the United States and later donated to the University of California, Los Angeles. A student at the university misplaced the violin in 1967 and the instrument went missing for 27 years. It reappeared when it was taken in for repairs and in 1995 UCLA successfully sued for ownership. The instrument was valued at around US$2,000,000 in 2014 (equivalent to US$2,570,000 in 2023).[1]
