Franz Jozef Hidin'
Da lesser-known 18th-century classical-music composer who was very bashful about showing himself in public, and so he had to have a courier deliver the sheet-music to the publisher after he'd composed said melodic artistry.
It's too bad that modern electronics and communications didn't exist back in Franz Jozef Hidin's time, or he could simply have faxed of emailed his priceless works of music to his publishers instead of having a courier hand-deliver them.
