Thomas Jefferson (1743-1826) was the third president of the United States, the author of the Declaration of Independence, and the founder of the University of Virginia. Among his proudest achievements was his Bill for Establishing Religious Freedom, passed by the General Assembly of Virginia in 1786, which became the first law of its kind in the United States. Also a noted architect and naturalist, Jefferson designed and built his home, Monticello, near Charlottesville, Virginia.
