George Washington, the first, was president at the time of the signing, while James Madison would go on to serve as the fourth president of the United State. President Madison, considered the Father of the U.S. Constitution, was the only delegate to attend every meeting. goes on to note that, “The journal that he [Madison] kept during the Constitutional Convention was kept secret until after he died. It (along with other papers) was purchased by the government in 1837 at a price of $30,000 (that would be $695,000 today).” Madison’s convention journal was finally published in 1840.

This state had the most signers of the Constitution

You might think that Virginia or New York had the most delegates sign the Constitution but 20 percent of the signers (eight of the 39) were from the state of Pennsylvania! Interestingly, while the small state of Delaware might seem rather insignificant to some today, Delaware had the second most delegates (five) sign the U.S. Constitution and it became the very first state when all 30 delegates of the Delaware Constitutional Convention unanimously ratified the U.S. Constitution on December 7, 1787. Delaware is rightly called The First State, but do you know the nicknames for all 50 States?

Did Alexander Hamilton sign the Constitution?
