Olivér Halassy

Olivér Halassy (né Haltmayer; 31 July 1909 – 10 September 1946) was a Hungarian water polo player and freestyle swimmer who competed at the 1928, 1932 and 1936 Summer Olympics.

Halassy lost his left leg below the knee when he was hit by a train at the age of 11. He later became the first amputee swimmer to compete in the Olympics. He was a member of the Hungarian water polo teams that won one silver and two gold medals in 1928, 1932 and 1936. He played all matches and scored three, eleven, and six goals, respectively.

Halassy won three European water polo titles, in 1931, 1934, and 1938. He also became European champion in 1500 metres freestyle swimming in 1931, a few hours after he helped his water polo team to victory. Nationally he won 25 swimming titles and set 12 records.
