How old was John Adams when he died?
He was 91 years old. He was born on October 30th, 1735 and he died at July 4th, 1826.
John Adams was born in 1767 and died in 1848. Do the math. 1848-1767= 81 years old. Yes it would be correct if John Adams was actually BORN in 1767 and died in 1848. He was not in fact born in 1767 nor did he die in1848. He was actually born in 1735 and died in 126 so that would make him 91 years old.
John Adams was born on October 30, 1735 and died on July 4, 1826 (same day that Thomas Jefferson died). John Adams is thought to have died of debility (old age; most likely heart failure caused by arteriosclerosis). He was, after all, almost 91 years of age at his death - an astonishingly old man for that period in history.
