Through these achievements and more, Jefferson was a great leader for the United States of America. (Wikipedia) A weird fact about Jefferson is that he also helped invent modern agricultural science and technology. He loved all kinds of science but he believed agriculture was the most important science. By himself, he re-engineered the plow according to scientific principles that came from Sir Isaac Newton, the inventor of mathematical physics. (Science Education) After president he left the office, he married a women named Martha Wayles Skelton, with whom he lived happily for ten years until she died. They had six children, but only two survived to adulthood. Jefferson never remarried after Martha. That shows that he was not only a loyal president but he was also a loyal husband. (Wikipedia)
