Shortly after Joseph Haydn died in 1809, two phrenologists dug up the composer’s corpse to determine whether his talent was somehow reflected in his cranium. Johann Peter, governor of a local prison, found indeed that “the bump of music” in Haydn’s skull was “fully developed,” and he proudly kept the skull in a box adorned with a golden lyre.
Eleven years later, Haydn’s old patron Prince Esterházy discovered the outrage while arranging to have Haydn’s remains transferred elsewhere, and the phrenologists were forced to stash Haydn’s skull briefly in a straw mattress while they passed a different one to Esterházy.
The real skull was bequeathed eventually to the Viennese Society of the Friends of Music and was reunited with its corpse only in 1954, 22 years after Esterházy’s descendant had built a marble tomb for the purpose. Even in death, there’s paperwork.
