Final answer:
The other prominent figure involved in The Duel with Aaron Burr, which led to a death at the age of 47, was Alexander Hamilton.
Step-by-step explanation:
The prominent figure involved with Aaron Burr in the historical event known as The Duel was Alexander Hamilton. On July 11, 1804, in Weehawken, New Jersey, Vice President Aaron Burr and former Secretary of the Treasury Alexander Hamilton engaged in a duel following years of mutual enmity. Their confrontation was the result of a long-standing political and personal animosity, exacerbated when Burr blamed Hamilton for his loss in the New York governor's race. The duel followed the traditional protocol with pistols, and while Hamilton's shot missed—likely intentionally—Burr's shot struck Hamilton, leading to his death the following day.
