Whose grave is widely said to carry a curse against whoever disturbs it?

William Shakespeare’s grave is said to carry a curse against whoever disturbs it.

Explanation:

William Shakespeare is widely regarded as the world’s greatest poet and dramatist. He is believed to be the best British writer of all times. Incurring the wrath of the dead is something one should avoid especially if there is a ghost you may not want to upset. It is Shakespeare who gave a curse on his grave at the "Holy Trinity Church" in "Stratford-upon-Avon".  In those days, the bodies are exhumed for research purposes or moved for accommodating more space for burials. Shakespeare did not want this to happen to his body. So, he had penned down a note that whoever moves his bones will be cursed.
