I don't know all who got a silver in the Olympics but I do know who got for gymnastics, Shawn Johnson
Kohei Uchimura
No 11 year old has won a gold medal in gymnastics at the Olympics. The youngest gold medal winning gymnast is Nadia Comaneci of Romania who was 14 years old when she won the uneven bars, balance beam, and individual all-around events at the 1976 Summer Games in Montreal. Luigina Giavotti was 11 years old when she won a silver medal in team all-around at the 1928 Summer Games in Amsterdam and Dimitrios Loundras of Greece was 10 years old when he won a bronze medal in team parallel bars at the 1896 Games in Athens.
