input: Barnard performed the world's first human-to-human heart transplant operation in the early morning hours of Sunday 3 December 1967. Louis Washkansky, a 54-year-old grocer who was suffering from diabetes and incurable heart disease, was the patient. Barnard was assisted by his brother Marius Barnard, as well as a team of thirty persons. The operation lasted approximately five hours.  Barnard stated to Washkansky and his wife Ann Washkansky that the transplant had an 80% chance of success. This has been criticised by the ethicists Peter Singer and Helga Kuhse as making claims for chances of success to the patient and family which were "unfounded" and "misleading".  Barnard later wrote, "For a dying man it is not a difficult decision because he knows he is at the end. If a lion chases you to the bank of a river filled with crocodiles, you will leap into the water, convinced you have a chance to swim to the other side." The donor heart came from a young woman, Denise Darvall, who had been rendered brain dead in an accident on 2 December 1967, while crossing a street in Cape Town. On examination at Groote Schuur hospital, Darvall had two serious fractures in her skull, with no electrical activity in her brain detected, and no sign of pain when ice water was poured into her ear. Coert Venter and Bertie Bosman requested permission from Darvall's father for Denise's heart to be used in the transplant attempt. The afternoon before his first transplant, Barnard dozed at his home while listening to music. When he awoke, he decided to modify Shumway and Lower's technique. Instead of cutting straight across the back of the atrial chambers of the donor heart, he would avoid damage to the septum and instead cut two small holes for the venae cavae and pulmonary veins. Prior to the transplant, rather than wait for Darvall's heart to stop beating, at his brother Marius Barnard's urging, Christiaan had injected potassium into her heart to paralyse it and render her technically dead by the whole-body standard. Twenty years later, Marius Barnard recounted, "Chris stood there for a few moments, watching, then stood back and said, 'It works.'"  Washkansky survived the operation and lived for 18 days, having succumbed to pneumonia as he was taking immunosuppressive drugs.

input: The Union of South Africa was born, and the Afrikaners held the key to political power, as the majority of the electorate. Although Botha was appointed prime minister of the new country, Smuts was given three key ministries: Interior, Mines, and Defence. Undeniably, Smuts was the second most powerful man in South Africa. To solidify their dominance of South African politics, the Afrikaners united to form the South African Party, a new pan-South African Afrikaner party.  The harmony and cooperation soon ended. Smuts was criticised for his overarching powers, and the cabinet was reshuffled. Smuts lost Interior and Mines, but gained control of Finance. This was still too much for Smuts' opponents, who decried his possession of both Defence and Finance: two departments that were usually at loggerheads. At the 1913 South African Party conference, the Old Boers (Hertzog, Steyn, De Wet), called for Botha and Smuts to step down. The two narrowly survived a confidence vote, and the troublesome triumvirate stormed out, leaving the party for good.  With the schism in internal party politics came a new threat to the mines that brought South Africa its wealth. A small-scale miners' dispute flared into a full-blown strike, and rioting broke out in Johannesburg after Smuts intervened heavy-handedly. After police shot dead twenty-one strikers, Smuts and Botha headed unaccompanied to Johannesburg to resolve the situation personally. Facing down threats to their own lives, they negotiated a cease-fire. But the cease-fire did not hold, and in 1914, a railway strike turned into a general strike. Threats of a revolution caused Smuts to declare martial law. Smuts acted ruthlessly, deporting union leaders without trial and using Parliament to absolve him and the government of any blame retroactively. This was too much for the Old Boers, who set up their own National Party to fight the all-powerful Botha-Smuts partnership.

input: Ambrose was the lone historian featured in the 1973-74 ITV television series, The World at War, which detailed the history of World War II.  He served as the historical consultant for the movie Saving Private Ryan. Tom Hanks, who starred in the movie, said he "pored over D-Day" and Band of Brothers in researching his role. Hanks also credited Ambrose's books with providing extensive detail, particularly regarding D-Day landings.  The HBO mini-series, Band of Brothers (2001), for which he was an executive producer, helped sustain the fresh interest in World War II that had been stimulated by the 50th anniversary of D-Day in 1994 and the 60th anniversary in 2004. Ambrose served as executive producer for Price for Peace, a documentary concerning the war in the Pacific theater during World War II, and for Moments of Truth, a TV documentary containing interviews with World War II veterans.  In addition, Ambrose served as a commentator for Lewis & Clark: The Journey of the Corps of Discovery, a documentary by Ken Burns. He provided commentary in twenty made-for TV documentaries, covering diverse topics, such as World War II, Lewis & Clark, and America's prominence in the 20th century. He also appeared as a guest on numerous TV programs or stations, including The Charlie Rose Show, C-Span programming, CNN programming, NBC's Today Show, CNBC's Hardball, and various programming on The History Channel and the National Geographic Channel. Ambrose's association with National Geographic stemmed, in part, from his designation as an Explorer-in-Residence by the Society.  In addition to his academic work and publishing, Ambrose operated a historical tour business, acting as a tour guide to European locales of World War II. Also, he served on the board of directors for American Rivers and was a member of the Lewis and Clark Bicentennial Council.
