Who wrote the US Constitution?

A man named Governor Morris of Pennsylvania was in charge of the

committee to draft the final copy of the Constitution. Other men

who had much to do with writing the Constitution included John

Dickinson, Governor Morris, Thomas Jefferson, John Adams, Thomas

Paine, Edmund Randolph, James Madison, Roger Sherman, James Wilson,

and George Wythe. Morris was given the task of putting all the

convention's resolutions and decisions into polished form. Morris

actually "wrote" the Constitution. The original copy of the

document is preserved in the National Archives Building in

Washington, D.C.

Jacob Shallus who, at the time, was assistant clerk of the

Pennsylvania State Assembly, and whose office was in the same

building in which the Convention was held, was given the task of

engrossing the Constitution prior to its being signed.

Here is more input from other WikiAnswers contributors:

• The U.S. Constitution is the work of several men, directly and

  indirectly. The three most notable persons whose work influenced

  the Constitution but who were not involved in its writing are

  Thomas Jefferson, John Adams and Thomas Paine. The group of men

  involved in the writing of the Constitution are generally referred

  to as the "framers".

• No single individual wrote it. Twelve of the thirteen states

  sent delegates to the Constitutional Convention to revise the

  Articles of Confederation and the entire convention worked on it.

  After the political questions were hashed out a 'committee of

  style' was formed to put the ideas into formal words. It is

  generally accepted that Governor Morris created most of the actual

  wording included in the final draft from the Committee of

  Style.

• The original copy of the document is preserved in the National

  Archives Building in Washington, D.C.

• The person most associated with authoring the US Constitution

  was James Madison, the fourth President of the United States.

  Primary Author: James Madison (drafted the Virginia Plan). He is

  known as "The Father of the Constitution." James Madison wrote the

  Constitution in 1787. The constitution wasn't passed until

  1788.

The US Constitution was written by the members of the

Constitutional Convention.
