Kennedy Sr. and Rose Fitzgerald, a sister of U.S. President John F. Kennedy and Senators Robert F. Kennedy and Ted Kennedy, and the wife of the Marquess of Hartington, heir apparent to the 10th Duke of Devonshire. When her father was serving as U.S. Ambassador to the United Kingdom, Kathleen made many friends in London and was the "debutante of 1938". Working with the Red Cross, she began a romantic relationship with Lord Hartington, whom she married in May 1944 much to the anger of her parents. He was killed on active service in Belgium only four months later. Kathleen died in a plane crash in 1948, flying to the south of France while on vacation with her new partner, the 8th Earl Fitzwilliam. The only family member to attend her funeral was her father, Joseph P. Kennedy. Her mother, Rose Kennedy waited 20 years to visit her daughter's grave, and even then it was a brief visit.

best_know_for: Daniel Boone, a bonafide legend during his own lifetime, was an American pioneer and frontiersman whose exploits made him one of the first folk heroes of the United States. Boone became famous for his exploration and settlement of what is now Kentucky, which was then beyond the western borders of the Thirteen Colonies. Despite resistance from American Indians, for whom Kentucky was a traditional hunting ground, in 1775 Boone blazed the Wilderness Road through the Cumberland Gap and into Kentucky. There he founded Boonesborough, one of the first English-speaking settlements west of the Appalachian Mountains. By the end of the 18th century, more than 200,000 people had entered Kentucky by following the route marked by Boone.

best_know_for: Leonardo da Vinci (Italian for “Leonardo from Vinci”) was an Italian painter, draftsman, sculptor, architect, and engineer whose skill and intelligence, perhaps more than that of any other figure, epitomized the Renaissance humanist ideal. His Last Supper (1495–98), Vitruvian Man (c. 1490) and Mona Lisa (c. 1503–19) are among the most widely popular and influential paintings of the Renaissance. His notebooks reveal a spirit of scientific inquiry and a mechanical inventiveness that were centuries ahead of their time. The world's most expensive painting to sell at auction is Leonardo da Vinci's Salvator Mundi, which sold for $450.3 million on November 15, 2017 at Christie's auction house.
