What is the name of the character who originally owned the Elder Wand before it was stolen?

The character who originally owned the Elder Wand before it was stolen was Antioch Peverell.

According to “The Tale of the Three Brothers,” Antioch was the eldest of three brothers who encountered Death and received the Elder Wand, the most powerful wand in existence. Proud of its power, he boasted that no wizard could defeat him. That arrogance made him a target: a rival murdered Antioch in his sleep and stole the wand.

The other two brothers were Cadmus Peverell, who received the Resurrection Stone, and Ignotus Peverell, who received the Cloak of Invisibility. These three objects became known as the Deathly Hallows. A common mix-up is identifying Dumbledore as the original owner. Dumbledore possessed the Elder Wand much later, after defeating its previous master, Gellert Grindelwald. Its allegiance later passed through Draco Malfoy and Harry Potter, showing that ownership depended on magical mastery rather than simple possession.
