On May 17, 1792, 24 New York stockbrokers met on Wall Street and signed the Buttonwood Agreement, a brisk two-sentence pact named for the buttonwood (American sycamore) tree where they liked to trade.

The rules were simple: deal only with one another, cutting out the auctioneers, and charge a minimum commission of 0.25% on every transaction. It was less a grand institution than a club for restoring trust after the financial panic of 1792, when reneged deals had spooked the young market.

Two sentences, twenty-four signatures, and the beginnings of Wall Street as we know it.

The arrangement formalized in 1817 as the New York Stock & Exchange Board, which adopted a constitution and membership rules. From that buttonwood handshake grew the New York Stock Exchange, now the largest exchange on Earth by the market value of its listed companies.
