...According to Braun, whose presser was translated by Ruud Paauw in the 2001 Journal of Olympic History, on Aug. 9 she was watching the 400m men's freestyle final from a section of stands reserved for foreign Olympic participants when she noticed two "young Americans" who seemed both out of place and to be monitoring her closely. As the race ended, she stood up and felt a stab in her left leg. The two Americans ahead of her vanished from the scene... Aaaaand here is Braun's version of the story, which she told the Dutch press when she got back home: "It was impossible to swim on the afternoon of the final of the 100 metres backstroke. They gave me very hot and very cold baths, but that did not help. I got a heavy fever, 42 degrees [Celsius]. A Dutch doctor came to see me and said that I had to go to the hospital immediately. There, four doctors examined my leg. I heard one of them say: 'But this is not an infection'. Then they realized that I could understand English and walked away to discuss the case somewhere else. Suddenly, I remembered the stab in the swimming stadium and the two American men. It must have happened there."...According to Braun, whose presser was translated by Ruud Paauw in the 2001 Journal of Olympic History, on Aug. 9 she was watching the 400m men's freestyle final from a section of stands reserved for foreign Olympic participants when she noticed two "young Americans" who seemed both out of place and to be monitoring her closely. As the race ended, she stood up and felt a stab in her left leg. The two Americans ahead of her vanished from the scene. Over the course of the next day her leg started seizing up, and by the 12th — the date of the backstroke final — Braun was in hospital.
The final saw Braun, roared on by the home crowd, survive a poor finish to hold off the challenge of King and her fellow Briton, [Joyce Cooper], to become the first Dutchwoman to win an individual Olympic event. Braun, whose mother was the coach to the Dutch team, attempted to defend her Olympic title four years later in Los Angeles but an apparent insect bite developed into a serious case of blood poisoning that kept her out of the final. After spending weeks in a Los Angeles hospital, Braun returned home to Rotterdam and gave a press conference where she alleged her illness was not caused by an insect but was the result of a deliberate attempt to injure her. Speculation involved a possible link to illegal betting. Another finalist in 1928 was the fourteen year old [Eleanor Holm] who began an international career that would veer between brilliance and controversy over the next decade.
