Mozart died on December 5, 1791, at age 35. The cause of death is uncertain, due to the limits of postmortem diagnosis. Officially, the record lists the cause as severe miliary fever, referring to a skin rash that looks like millet seeds. Since then, many hypotheses have circulated regarding Mozart's death. Some have attributed it to rheumatic fever, a disease he suffered from repeatedly throughout his life. It was reported that his funeral drew few mourners and he was buried in a common grave. Both actions were the Viennese custom at the time, for only aristocrats and nobility enjoyed public mourning and were allowed to be buried in marked graves. However, his memorial services and concerts in Vienna and Prague were well attended. After his death, Constanze sold many of his unpublished manuscripts to undoubtedly pay off the family’s large debts. She was able to obtain a pension from the emperor and organized several profitable memorial concerts in Mozart’s honor. From these efforts, Constanze was able to gain some financial security for herself and allowing her to send her children to private schools.
