His father Peter Jefferson was a successful planter and surveyor and his mother Jane Randolph a member of one of Virginia’s most distinguished families. Having inherited a considerable landed estate from his father, Jefferson began building Monticello when he was twenty-six years old. Three years later, he married Martha Wayles Skelton, with whom he lived happily for ten years until her death. Their marriage produced six children, but only two survived to adulthood. Jefferson, who never remarried, maintained Monticello as his home throughout his life, always expanding and changing the house.
President Thomas Jefferson
Perhaps the most notable achievements of his first term were the purchase of the Louisiana Territory in 1803 and his support of the Lewis and Clark expedition. His second term, a time when he encountered more difficulties on both the domestic and foreign fronts, is most remembered for his efforts to maintain neutrality in the midst of the conflict between Britain and France; his efforts did not avert war with Britain in 1812.
