Back in the 1800s, composer Franz Liszt was worshiped like a rock star. In fact, he received so many requests for locks of his hair that he eventually bought a dog, only to snip off patches of its fur to send to his admirers.

During Beethoven’s autopsy, one doctor took his ear bones, locks of hair were clipped, and when his body was exhumed later in the 1800s, fragments of his skull were taken.
