Both were mold-breaking former heads of state who reshaped their own countries and the world. Nelson Mandela, revered for his efforts to end apartheid in South Africa, and Margaret Thatcher, the "Iron Lady" who imposed her will on Britain's politics and economy, were among notables who died in 2013.
Mandela, who died Dec. 5 at age 95, was considered a master of forgiveness. He became South Africa's first black president after spending 27 years in prison for championing equality against the white-minority government, and he inspired the world by seeking a relatively peaceful transition of power.
As Britain's only female prime minister, Thatcher ruled for 11 years and showed an unshakable faith in the free market, leaving behind a leaner government and more prosperous nation. While she had fierce critics, praise for her leadership came in from around the world when she died in April at 87.
Other political figures who died this year included Venezuelan leader Hugo Chavez, former Italian premier Giulio Andreotti, Poland's ex-prime minister Tadeusz Mazowiecki, France's Pierre Mauroy, and Hungary's Gyula Horn, prominent mayors of New York and Beijing, Ed Koch and Chen Xitong, and former U.S. Senators Frank Lautenberg and Harry F. Byrd.
Also dying in 2013 was a man whose invention you may hold as you read this. Doug Engelbart, who died in July, invented the computer mouse and developed other technology that changed the way people work, play and communicate. Others from the world of science and technology who died this year included the Manhattan Project's Donald F. Hornig, Nobel Prize winners Frederick Sanger, Robert Edwards and Kenneth Wilson, and audio pioneers Ray Dolby and Amar Bose and astronauts C. Gordon Fullerton and Scott Carpenter.
In arts and entertainment, this year saw the death of one who was hugely influential though not technically an entertainer at all. Roger Ebert, who died in April, was America's most popular film critic, telling audiences which movies to see or avoid with his famous thumbs-up or thumbs-down reviews.
Others from the entertainment world who died this year included actors James Gandolfini, Jane Kean, Annette Funicello, Jean Stapleton, Bonnie Franklin, Cory Monteith, Frank Thornton and Conrad Bain, as well as the swimming star Esther Williams and the Bollywood villain Pran. Musicians included George Jones, Van Cliburn, Lou Reed, Donald Byrd, Ray Manzarek, Bebo Valdes, Mindy McCready, Chrissy Amphle and Chris Kelly. Among others: writer Tom Clancy, director Nagisa Oshima and ballerina Maria Tallchief.
