best_know_for: Michael LeMoyne Kennedy was born into a very public family as Robert F. and Ethel Kennedy's middle of 11 children. He graduated from Harvard in 1980 and then went to law school at the University of Virginia, where he earned a law degree in 1984. In 1988 he took over as chairman of Citizens Energy Corp., the nonprofit fuel company founded by his brother, Congressman Joseph P. Kennedy II, that discounts home heating fuel for the poor. He also chaired Citizens Conservation Corp., which provided energy consulting services to low-income, multi-family housing. Through Citizen's Energy subsidiaries, Kennedy also coordinated relief missions to West Africa in 1989 and 1992, founded the U.S.-Angola Chamber of Commerce and helped establish a Catholic university in that country. Kennedy also co-chaired the Walden Woods Project, an effort to preserve a forest near Walden Pond in Concord, and Stop Handgun Violence Inc., a group that works to raise awareness about handguns. All that work, however, was overshadowed when reports said he had a 3-year affair with his children's 14-year-old baby sitter. Robert F. Kennedy's 39-year-old son died on New Year’s Eve Day 1997, playing football while skiing Aspen Mountain’s Copper Bowl. It was a game that the Kennedy family had enjoyed for over three decades, and was considered daring, if not dangerous. This time, Kennedy was caught off-balance and too close to the treeline, lost an edge, and went into a tree head first. He had not been wearing a helmet. He was the second of Robert and Ethel Kennedy's sons to die young. In 1984 David Anthony Kennedy died of a drug overdose at age 24.

claim_to_fame: Historical Figure

best_know_for: Kathleen Agnes Cavendish, Marchioness of Hartington (née Kennedy) also known as "Kick" Kennedy was an American socialite. She was the second daughter of Joseph P. 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.

age: 67

cause_of_death: Stroke

claim_to_fame: Historical Figure

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.
