This is probably common knowledge to Americans, but I noticed that the latest amendment on the commit log was written by James Madison. I was confused as to how that came about so recently and found on the wikipedia page:

>It was submitted by the 1st Congress to the states for ratification on September 25, 1789, along with eleven other proposed amendments. While ten of these twelve proposals were ratified in 1791 to become the Bill of Rights, what would become the Twenty-seventh Amendment and the proposed Congressional Apportionment Amendment did not get ratified by enough states for them to also come into force with the first ten amendments.

> The proposed congressional pay amendment was largely forgotten until 1982, when Gregory Watson, a 19-year-old sophomore at the University of Texas at Austin, wrote a paper for a government class in which he claimed that the amendment could still be ratified. A teaching assistant graded the paper a "C" and an appeal to the professor, Sharon Waite, failed, motivating Watson to launch a nationwide campaign to complete its ratification.[1] The amendment eventually became part of the United States Constitution, effective May 5, 1992,[2] completing a record-setting ratification period of 202 years, 7 months, and 10 days
