Who is the person whose grave is still empty?

As we all the humanity must have to die one day but if you have knowledge about the history then you might know that in the past ages one person who died but his grave is still empty. Can anyone tell the name of that person? If anyone will tell the name it would be amazing for me. All the graves of the people are filled but only one grave is still empty. Plz answer me this.Image is taken from google image.
