First perfect ten - Nadia Comaneci - Montreal 1976 Olympic Games
Romanian athlete Nadia Comaneci took up the sport of gymnastics aged six, becoming one of the first students at a school founded by coach Béla Károlyi. In 1975, 13-year-old Comaneci won gold in every event at the European Championships except the floor exercise.
A year later in Montreal, she became the first gymnast in Olympic history to be awarded the perfect score of 10.0 for her performance on the uneven bars. She went on to record the perfect 10.0 six more times and became the youngest all-around Olympic gold medallist ever.
