Linford Christie sprinted to 100m gold for Britain at an Olympic Games best remembered for America's basketball dream team.
In another Games affected by non-sporting issues, Romanian 14-year-old gymnast Nadia Comaneci caused a sensation on the uneven bars when she was awarded the first-ever perfect score of 10.0.
Yun is the latest talent to emerge from South Korea's production line of excellent female archers.
As a 23-year-old at the Beijing Olympics, she was part of her country's gold-medal winning team and added a bronze in the individual competition.
She has since ascended to the top of the world rankings and took double gold - team and individual - at the Asian Games in 2010.
Yun will arrive in London with plenty of pressure on her shoulders as South Korea's women look to continue their remarkable run of success.
They have won team gold at the last three Games and six of the last seven individual golds.
