In the summer of 1787, a group of delegates from the 13 former American Colonies met in Philadelphia to hammer out a new and improved constitution for their young country. This article is a who's who synopsis of the fifty-five official delegates that participated and their family history links.

With the exception of Rhode Island, which refused to participate, the states had originally appointed 70 representatives to the Convention, but a number of the appointees did not accept or could not attend, leaving 55 delegates who would ultimately craft the Constitution.

Almost all of the 55 delegates had taken part in the Revolution, with at least 29 having served in the Continental forces, most in positions of command. All but two or three had served in colonial or state government during their careers. The vast majority (about 75%) of the delegates were or had been members of the Confederation Congress, and many had been members of the Continental Congress during the Revolution. Several had been state governors. Just two delegates, Roger Sherman and Robert Morris, would be signatories to all three of the nation’s founding documents, the Declaration of Independence, the Articles of Confederation, and the Constitution.

More than half of the delegates had trained as lawyers (several had even been judges), although only about a quarter had practiced law as their principal means of business. There were also merchants, manufacturers, shippers, land speculators, bankers or financiers, two or three physicians, a minister, and several small farmers. Of the 25 who owned slaves, 16 depended on slave labor to run the plantations or other businesses that formed the mainstay of their income. Most of the delegates were landowners with substantial holdings, and most, with the possible exception of Roger Sherman and William Few, were very comfortably wealthy. George Washington and Gouverneur Morris were among the wealthiest men in the entire country.

The names of several prominent Founders are notable for their not having participated in the Constitutional Convention. Thomas Jefferson was abroad, serving as the minister to France. John Adams was in Britain, serving as minister to that country, but he wrote home to encourage the delegates. Patrick Henry refused to participate because he "smelt a rat in Philadelphia, tending toward the monarchy." Also absent were John Hancock and Samuel Adams. Many of the states’ older and more experienced leaders may have simply been too busy with the local affairs of their states to attend the Convention, which had originally been planned to strengthen the existing Articles of Confederation, not to write a constitution for a completely new national government.
