1743 – 1826
Thomas Jefferson (1743–1826) was an American Founding Father, principal author of the Declaration of Independence, and third President of the United States. Drawing heavily on Locke, the Scottish Enlightenment, and classical republicanism, he developed a natural rights framework grounding legitimate government in individual consent and liberty. His thought persistently navigated the tension between atomistic individualism and the civic virtue required to sustain a self-governing republic.
