In his first term of presidency Jefferson bought the Louisiana Purchase from France, doubling the size of the US. Next Jefferson sent Meriwether Lewis and William Clark on a quest to find the Pacific Ocean in 1803-1806. Jefferson also invented the moldboard plow, which was a great improvement on the already standard farming plow; the wheel cipher, and developed his own design on the concept of the spherical sundial. He was the first man to say that tomatoes weren't poisonous. He also made the light bulb.
Thomas Jefferson wrote the Declaration of Independence and had also sent the 2 great explorers Lewis and Clark to explore the Louisiana Purchase
