The Founder that included the idea of natural rights when he wrote the Declaration of Independence was Thomas Jefferson.
Thomas Jefferson was the third president of the United States of America, occupying the position between 1801 and 1809. He is considered one of the founding fathers of the nation.
He is a great eminence in the history of the United States because he was the main author of the Declaration of Independence of 1776. Jefferson was one of the most influential Founding Fathers, known for his promotion of the ideals of republicanism in the United States.
Jefferson believed that each individual has "certain inalienable rights." That is, these rights exist, with or without government, man can not create, take, or throw them away. It is the right of "freedom".
A proper government, for Jefferson, is one that not only prohibits individuals in society from violating the freedom of other individuals, but also one that stops when it comes to diminishing individual freedom.
