Who was the skilled craftsman from Tyre who worked on the temple?

Answer: Hiram (Huram)

King Solomon sent for Hiram (or Huram), a skilled craftsman in bronze.

“Now King Solomon sent to bring Huram from Tyre. He was the son of a widow from the tribe of Naphtali, and his father was a man of Tyre, a craftsman in bronze. Huram had great skill, understanding, and knowledge for every kind of bronze work. So he came to King Solomon and carried out all his work.”— 1 Kings 7:13-14 (BSB)
