This geriatric profile specifically reflects the impressive achievements of Thomas Jefferson during the years of his retirement (ages 66-83) following a distinguished political career culminating in the Presidency. President Monroe sought his advice even after the age of 80, and Jefferson's reasoning was instrumental in the formulation of the Monroe Doctrine. Education was a foremost priority in retirement. He was responsible for the establishment of the University of Virginia, in which his versatility was manifested as architect, builder, and fund raiser. Jefferson was a man of breadth and extraordinary vision for his time, and has come to be known as the "Father of American Democracy." The basic concepts of his philosophy, including the realm of aging, remain valid today-150 years after his passing.
