tried to achieve self-sufficiency with wheat, vegetables, flax, corn, hogs, sheep, poultry, and cattle to supply his family, slaves, and employees, but he lived perpetually beyond his means and was always in debt. In the field of architecture, Jefferson helped popularize the Neo-Palladian style in the United States utilizing designs for the Virginia State Capitol, the University of Virginia, Monticello, and others. It has been speculated that he was inspired by the Château de Rastignac in south-west France—the plans of which he saw during his ambassadorship—to convince the architect of the White House to modify the South Portico to resemble the château. Jefferson mastered architecture through self-study, using various books and classical architectural designs of the day. His primary authority was Andrea Palladio's 1570 The Four Books of Architecture, which outlines the principles of classical design. He was interested in birds and wine, and was a noted gourmet; he was also a prolific writer and linguist, and spoke several languages.

American Philosophical Society Jefferson was a member of the American Philosophical Society for 35 years, beginning in 1780. Through the society he advanced the sciences and Enlightenment ideals, emphasizing that knowledge of science reinforced and extended freedom. His Notes on the State of Virginia was written in part as a contribution to the society. He became the society's third president on March 3, 1797, a few months after he was elected Vice President of the United States. In accepting, Jefferson stated: "I feel no qualification for this distinguished post but a sincere zeal for all the objects of our institution and an ardent desire to see knowledge so disseminated through the mass of mankind that it may at length reach even the extremes of society, beggars and kings." Jefferson served as APS president for the next eighteen years, including through both terms of his presidency. He introduced Meriwether Lewis to the society, where various scientists tutored him in preparation for the Lewis and Clark Expedition. He resigned on January 20, 1815, but remained active through correspondence. Linguistics Jefferson had a lifelong interest in linguistics, and could speak, read, and write in a number of languages, including French, Greek, Italian, and German. In his early years, he excelled in classical language while at boarding school where
