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:
“Friendship can only exist between persons with similar interests and points of view. Man and woman by the conventions of society are born with different interests and different points of view.”
—J. August Strindberg (1849–1912)
“Opinions have vested interests just as men have.”
—Samuel Butler (1835–1902)
“Love and work are viewed and experienced as totally separate activities motivated by separate needs. Yet, when we think about it, our common sense tells us that our most inspired, creative acts are deeply tied to our need to love and that, when we lack love, we find it difficult to work creatively; that work without love is dead, mechanical, sheer competence without vitality, that love without work grows boring, monotonous, lacks depth and passion.”
—Marta Zahaykevich, Ucranian born-U.S. psychitrist. “Critical Perspectives on Adult Women’s Development,” (1980)
