One of the strangest Cholera stories concerns the Russian composer Tchaikovsky who died from cholera in 1893, nine days after the premiere of his Sixth, and probably most famous, Symphony, the Pathétique.
There are no end of theories about how and why this occurred, ranging from an accident to suicide to forced suicide.

Tchaikovsky's (1840-1893) death: cholera, suicide, or both?, or, my favorite, the Straight Dope: How did Tchaikovsky really die?
And then there's the question of whether the Pathétique was written as a farewell to the world.
