Thomas Jefferson Inventions

Thomas Jefferson was the 3rd president of the United States, he was president gtom 1801-1809. He was the first Republican President, he was born on April 13, 1743 and died July 4, 1826 (The same day John Adams died). Not only was Jefferson a great president but he also came up with numerous inventions throughout his lifetime. He was one of Virginia's largest planters, and he thought agriculture was extremely important. Jefferson brought many plants from other countries into the united states. He also exchanged farming advice and ideas with other farmers. One agricultural invention that Jefferson made was a plow that would delve deeper than a regular plow. He also developed a plow specifically designed for hillside plowing. His plow designs were often based on mathematical formulas.

The Wheel Cipher was another one of Jefferson's many inventions. This invention was made between the years 1792 and 1793 when Jefferson was the United States' secretary of state.

The country was currently faced with controversial foreign policy and national security problems. The purpose of the Wheel Cipher is so that a person could scramble and unscramble letters in order to code messages. It was made of 26 circular wooden pieces that were threaded onto a iron spindle. On each wheel all 26 letters of the alphabet were inscribed.

Jefferson also invented the Great Clock that is at the entrance of the hall of Monticello. You can read the clock from both sides to encourage exercise and productivity. There is no minute hand on the clock because the hour hand is precise enough to tell the time. The Great Clock is connected to a large copper gong and could be heard from the University of Virginia. This is one of Jefferson's most visible inventions.
