Which two former U.S. presidents died on July 4, 1826, the 50th anniversary of the Declaration?

John Adams and Thomas Jefferson died on July 4, 1826, the 50th anniversary of the Declaration of Independence.

Adams and Jefferson were both Founding Fathers, presidents, and important participants in the independence movement. Adams served as a leading advocate for independence, while Jefferson drafted the Declaration’s initial text. Their deaths occurred exactly 50 years after Congress adopted the document.

Jefferson died in Monticello, Virginia, on July 4, 1826. Adams died later that day in Quincy, Massachusetts. According to the commonly reported account, Adams’s final words included the mistaken belief that Jefferson still lived.

Their simultaneous deaths became one of the most memorable coincidences in American founding history. The event also shaped later anniversary traditions, even though the 1826 observance itself was not a major government-sponsored national celebration.
