Godelot

Godelot, described as an "unpleasant character", was a wizard who once mastered the Elder Wand. Godelot, having considered the Elder Wand an instructor, had used his knowledge of the Wand's powers to write Magick Moste Evile, a book that contained information on dark magic. Godelot perished on his own cellar, where he was locked by his son, Hereward Godelot, who did this to gain mastership of the Elder Wand.
