Almost all of these 55 delegates participated in the War of Independence, and 29 of them served in the mainland army, most of whom were officers. Except for two or three representatives, they all served in colonial or independent state governments. About three-quarters of the delegates were or were members of the Confederate Congress. Most of them were members of the Continental Congress during the War of Independence, and several of them were governors. Only roger sherman and robert morris have successively signed three landmark documents in the history of the founding of the United States, namely, the Declaration of Independence, the Confederate Regulations and the Constitution.
More than half of the delegates have received professional legal training and worked as lawyers or judges, but only about a quarter of them make a living from it. Other occupations of the delegates are: businessmen, ship owners, factory owners, bankers, financiers, farmers, land speculators, doctors and priests. Among them, 25 people own slaves, and 16 people rely on slaves as capital for developing other businesses. Most of them own a lot of land, and most of them live a very rich and comfortable life. George Washington and Gouvernier Morris were the richest people in America at that time.

Several of the most famous American Founding Fathers did not attend the Constitutional Convention. For example, Thomas Jefferson was the French ambassador at that time (however, in a letter he wrote to john adams, he described the delegates' praise of the Constitution as a "genius move"), while john adams was the ambassador to Britain, and he also wrote to encourage the delegates. Patrick Henry called the meeting "full of the stench of monarchy" and refused to attend, as did john hancock and samuel adams. Many experienced senior representatives from more States were unable to attend mainly because of local affairs. They mainly planned to amend the Confederate regulations rather than form a new government.
