Who was the first person to score a perfect 10 in Gymnastics at the Olympic Games?

That was Nadia Comaneci at the 1976 Summer Games in Montreal.

Yes it was Nadia Comaneci at the 1976 Summer Games in Montreal, Mexico and Cristina Rubio: at the age of 13.

NO! Firstly, Nadia was 14, not 13, when she received her perfect 10 at the Montreal Olympics to become the first female gymnast to receive a perfect 10.

Albert Sequin received the first ever gymnastics perfect 10, 52 years earlier at the 1924 Paris Summer Olympics for the side vault.
