Thomas Jefferson is also reported to be 6 feet 2 inches. This puts him tied with FDR and a few other presidents. Jefferson was the primary author of the Declaration of Independence before serving as the third president of the United States of America. He entered office on March 4, 1801, and served until March 4, 1809. Before he was president, Jefferson served as Vice President to John Adams and the Secretary of State under George Washington.
As President, Jefferson doubled the size of the United States by acquiring the Louisiana territory via the famous Louisiana Purchase. The land was purchased from France, run by Napoleon Bonaparte at the time, for $15 million and consisted of 827,987 square miles. The treaty that sealed the deal was signed on April 30, 1803, and the purchase was ratified by the Senate on October 20, 1803.
After acquiring the Louisiana territory, Jefferson convinced Congress to fund the exploration and mapping of the new territory by Meriwether Lewis and William Clark. Lewis and Clark lead the Corps of Discovery all the way to the Pacific Ocean and brought back a treasure trove of knowledge in regards to science, geography, and even some Native American tribes. The expedition began in May 1804 and ended in September 1806.
