Jared Ingersoll was born on October 24, 1749 in New Haven, Connecticut. His name was from the namesake of his father, Jared Ingersoll, who was known for his dynamic participation as the Connecticut's envoy to London. Jared Ingersoll was a jurist, author and a member of Continental Congress at the same time. Although he was born from the state of Connecticut, he was more known as a state attorney general who served Philadelphia from 1791-1800. Furthermore, he is also the U.S lawyer for Pennsylvania from the years 1800-1801. For a short period of time, he also served as the presiding judge at the Philadelphia district court in the years 1821-1822.

Jared Ingersoll became a delegate to the Continental Congress and affirmed with his signature the U.S Constitution for the state of Pennsylvania. While his father's career was not that successful, Jared Ingersoll managed to take totally different platforms. After he graduated in 1766 from one of the world's most prestigious university, the Yale University, he then decided to go abroad. Before the revolution, he was sent to London as his father told him to do so to further his study at the Middle Temple and to escape the growing political tension at the same time. In the year 1776, he traveled around Europe in favor of independence and disregarded the Loyalist point of views of his father. It is because after his preparation as a lawyer, he was convinced that the problems of each newly independent state in the U.S were the results of insufficiency of the Articles of Confederation.

He went back to Philadelphia in the year 1778 and was confirmed as a Patriot. He received helpful and encouraging support from his very influential friends enabling him to easily establish his own name in the profession. In just a short period of time, he then joined the pursuit as one of the delegate of the Continental Congress during 1780-1781. He had always been an enthusiastic supporter of strong central authority in political affairs. One of his proposals then was primarily for constitutional reforms. Nevertheless, just like some of his fellows at the Constitutional Convention, he firmly believed that his reforms can only be achieved with simple modification of the articles.

After a few weeks of debate, he came to notice that a revised document is highly necessary. Conversely, Ingersoll's main contribution for the cause of constitutional government came not at some point in the Convention itself but sooner during an extensive and illustrious legal career when he facilitated to define most of the principles being enunciated in Philadelphia.

While serving Connecticut, he became an area collector and a supporter of the Stamp Act. But as the conflict from New England began to widely spread, fuming colonist met Ingersoll across the roads outside Hartford. That was the time when protesters stipulated his resignation. Together with the protesters, he publicly surrendered his title. One of the very controversial cases he entered was a landmark case in state's rights where he represented Georgia during Chisholm v. Georgia in the year 1793. The court went against him believing that a state might be sued in the Federal Court by a citizen of the other state. The reversal of this state sovereignty concept was later canceled by the 11th Amendment of the constitution. Being also a representative of Hylton in Hylton v. US in the year 1769, he indulged himself the first challenge to constitutionally of an act of the Congress. With this, the Supreme Court supported the government to implement tax on carriages.

At the Convention, Jared Ingersoll was one of those who affirmed to do some revisions of the existing Articles of Confederation. At the end however, he joined the majority and half-heartedly supported the plan to create a new federal government. Despite his excellent reputation as a lawyer, he do not often participate in the debates in the convention, nonetheless, he was able to consistently attend all of its sessions.

When the new national government was finally established, Jared Ingersoll went back to his profession as a lawyer. Aside from few digressions in some political issues, he became a member of the Common Council of Philadelphia in the year 1789. As a strong federalist in 1800, he considered the election of Thomas Jefferson as a "great subversion". He also joined the Federalist Party running for the position of Vice President with DeWitt Clinton for the U.S presidential election on the year 1812. Unfortunately, James Madison and Elbridge Gerry defeated his vote counts.

This great man from Connecticut, Jared Ingersoll, died in on October 22, 1822 in Philadelphia. He was buried at the First Presbyterian Church cemetery, although the cause of his death is still unknown to this day.
