who created the constitution of the united states
United States Constitution On the appointed day, May 14, 1787, only the Virginia and Pennsylvania delegations were present, and so the convention's opening meeting was postponed for lack of a quorum.[26] A quorum of seven states met and deliberations began on May 25. Eventually twelve states were represented; 74 delegates were named, 55 attended and 39 signed.[27] The delegates were generally convinced that an effective central government with a wide range of enforceable powers must replace the weaker Congress established by the Articles of Confederation. Their depth of knowledge and experience in self-government was remarkable. As Thomas Jefferson in Paris wrote to John Adams in London, "It really is an assembly of demigods."
