In 1767 at 11 years of age, composer Wolfgang Amadeus Mozart contracted smallpox, allegedly causing him temporary blindness. Although now eradicated, smallpox in those days had a high mortality rate, and the history of classical music would have been very different if Mozart had become permanently blind, or died, as a result of the disease.
