Interests and Activities
Jefferson was a farmer, with a lifelong interest in mechanical innovations, new crops, soil conditions, his gardens, and scientific agricultural techniques. His main cash crop was tobacco, but its price was usually low and it was rarely profitable. He tried to achieve self-sufficiency with wheat, vegetables, flax, corn, hogs, sheep, poultry and cattle to feed and clothe his family, slaves and white employees, but he had cash flow problems and was always in debt.
Jefferson was an accomplished architect who helped popularize the Neo-Palladian style in the United States. Jefferson was interested in birds and wine, and was a noted gourmet. Jefferson was a prolific writer. He learned Gaelic to translate Ossian, and sent to James Macpherson for the originals.
Jefferson invented many small practical devices and improved contemporary inventions. These include the design for a revolving book-stand to hold five volumes at once to be viewed by the reader. Another was the "Great Clock", powered by the Earth's gravitational pull on Revolutionary War cannonballs. Its chime on Monticello's roof could be heard as far as the University of Virginia. Louis Leschot, a machinist, aided Jefferson with the clock. Jefferson invented a 6 in (15 cm) long coded wooden cipher wheel, mounted on a metal spindle, to keep secure State Department messages while he was Secretary of State. The messages were scrambled and unscrambled by 26 alphabet letters on each circular segment of the wheel. He improved the moldboard plow and the polygraph, in collaboration with Charles Willson Peale.
As Minister to France, Jefferson was impressed by France's military standardization program known as the Système Gribeauval. As president, he initiated a program at the Federal Armories to develop interchangeable parts for firearms. Although not realized in Jefferson's lifetime, the concept of interchangeable parts eventually led to modern industry and was a major factor in the United States' industrial power by the late 19th century.
Jefferson can also be accredited as the creator of the swivel chair, the first of which he created and used to write much of the Declaration of Independence.

Famous quotes containing the words interests and, interests and/or activities:
“Consider any individual at any period of his life, and you will always find him preoccupied with fresh plans to increase his comfort. Do not talk to him about the interests and rights of the human race; that little private business of his for the moment absorbs all his thoughts, and he hopes that public disturbances can be put off to some other time.”
—Alexis de Tocqueville (1805–1859)
“It is ultimately in employers’ best interests to have their employees’ families functioning smoothly. In the long run, children who misbehave because they are inadequately supervised or marital partners who disapprove of their spouse’s work situation are productivity problems. Just as work affects parents and children, parents and children affect the workplace by influencing the employed parents’ morale, absenteeism, and productivity.”
—Ann C. Crouter (20th century)
“The interpretation of dreams is the royal road to a knowledge of the unconscious activities of the mind.”
—Sigmund Freud (1856–1939)
