Adrianus de Jong

Adrianus Egbert Willem “Adriaan” “Arie” de Jong (21 June 1882 – 23 December 1966) was a fencer who competed at five Olympic Games.
However, he had his greatest international success with the sabre, where he won the first two World Championships in 1922 and 1923.
With the épée, he won bronze at the 1912 Olympics and silver at the 1922 world championships.
During the individual sabre event at the 1924 Olympics, he reached the semi-finals against Hungarian Sándor Pósta and was leading by three hits when an audience member fell through his chair. This distracted the jury, who failed to see De Jong’s decisive hit. Disrupted, De Jong lost the bout. De Jong eventually finished fifth (one ahead of eventual seven-time Danish Olympian Ivan Joseph Martin Osiier) while Pósta went on to win gold.
