One of few athletes to receive the Olympic Diploma of Merit, Ivan Osiier represented his country in seven Olympic Games between 1908 and 1948. He missed only the 1936 Games, when he refused to participate in Berlin as a protest against the Nazis. He has participated in more Olympiads than any other athlete.
Osiier won his only Olympic medal in 1912, a silver in Individual Epee, at the Stockholm Games.
Dr. Osiier won a total of 25 Danish National Championships in all three fencing weapons—foil, epee, and sabre. He was also Scandinavian Foil titleholder in 1920, 1921, 1923, 1927, 1929, and 1931; he was Epee Champion in 1920; and he was Sabre Champin in 1921, 1923, 1927, 1929, 1931, and 1933.
Osiier began his athletic career as an oarsman and achieved considerable renown in the sport before he turned to fencing. He was a longtime head of the Denmark Fencing Federation.
