No, Abraham Baldwin did not sign the Declaration of Independence. While he was an important figure in American history, particularly in the state of Georgia, he was not a member of the Continental Congress at the time the Declaration was adopted in 1776.
Baldwin was a delegate to the Constitutional Convention in 1787 and played a significant role in shaping the U.S. Constitution. He later became a U.S. senator and was instrumental in the establishment of the University of Georgia, but his political activities occurred after the Declaration was signed.
