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/or activities:
“Unfortunately, many things have been omitted which should have been recorded in our journal; for though we made it a rule to set down all our experiences therein, yet such a resolution is very hard to keep, for the important experience rarely allows us to remember such obligations, and so indifferent things get recorded, while that is frequently neglected. It is not easy to write in a journal what interests us at any time, because to write it is not what interests us.”
—Henry David Thoreau (1817–1862)
“As life developed, I faced each problem as it came along. As my activities and work broadened and reached out, I never tried to shirk. I tried never to evade an issue. When I found I had something to do—I just did it.”
—Eleanor Roosevelt (1884–1962)
