Two athletes have won Summer Olympic gold medals competing for two different nations. Daniel Carroll first won gold in rugby union representing Australia at London 1908 and then again at Antwerp 1920 for the United States after he had stayed in the country following a tour there. The Georgian-born Kakhi Kakhiashvili won his first gold medal in men’s weightlifting under-90 kilograms competing as part of the Unified Team at Barcelona 1992 and later as a Greek citizen at Atlanta 1996 and Sydney 2000 in the under-99kg and under-94kg categories.

Aileen Riggin was the first-ever female Olympic diving champion at Antwerp 1920, winning shortly after having first taken up the sport following her recovery from the Spanish flu. The American was only 14 years and 120 days old when she won a gold medal in the women's 3 metre springboard diving event in the Belgian city, also making her at the time the youngest female Olympic champion. Not only was Riggin the youngest gold medallist at the 1920 Olympics, but she was also the shortest, at only 4ft 8in tall and weighing just 65 pounds. She remains the United States' smallest Olympic champion.
