Which of these men was NOT a U.S. President?

Benjamin Franklin was a highly influential Founding Father and played a significant role in the American Revolutionary War, but he did not hold the office of President of the United States. Franklin was known for his work as a statesman, inventor, and diplomat, contributing to the drafting of the Declaration of Independence and the U.S. Constitution. His legacy is immense in American history, but it is important to note that he never served as the President.

In contrast, George Washington, Thomas Jefferson, and Abraham Lincoln were all Presidents who helped shape the nation through their terms in office. Washington was the first President, Jefferson the third, and Lincoln the sixteenth, each leaving a distinct mark on American history and governance.
