Fëanor

Fëanor was a Ñoldorin Elf, second King of the Noldor, and one of the Elven kindred that departed from Valinor in the land of Aman, where they had lived with the Valar.

He was born in Valinor, the only child of Finwë, King of the Ñoldor, and Finwë's first wife Míriel Therindë. He was a craftsman, gem-smith, and warrior, the maker of the Silmarils and inventor of the Tengwar script. He was also the creator of the palantíri.

Fëanor was made the mightiest in all parts of body and mind; countenance, understanding, skill, and subtlety, of all the Children of Ilúvatar. However his personality was riddled with flaws, foremost among them selfishness and pride, which would lead him to bring terrible anguish and turmoil to his people.
