Diplomat, politician, writer, gardener, president, philosopher, jurist, and
             architect are just a few of the honorable titles achieved by Thomas Jefferson
             during his lifetime. However, one title that many people forget when thinking of
             the third President of the United States is inventor. Jefferson had a passion for
             creating things that could be used by the average person in order to make life
             just a little bit easier. Jefferson was very interested in agriculture, in fact, he

             in order to send and receive messages without interpretation by the enemy.
             Some of his inventions had no meaningful purpose except for his own personal
             pleasure. For example, Jefferson invented a revolving bookstand that could hold
             five books all capable of being reached at any time. In 1804, Jefferson created
             "automatic" double-doors. The doors were controlled by an operating
             mechanism that allowed both doors to move when one was opened or closed. Of
             all of Jefferson's inventions, the most visible was the Great Clock. Although it
             had no minute hand, the hour hand was capable of providing the needed
             accuracy for time as well as the date. Jefferson also buil...
