Oswaldo Domingues competed in the 1936 Olympics, representing the Brazilian Confederation of Sport (CBD). In that year there was a split between the CBD and the Brazilian Olympic Committee (COB), and thus Domingues’s name did not appear in the record of the COB until it was corrected in 2006. In 2006 the committee sent him a letter acknowledging their mistake, and his absence in their book Dream and Achievement. Domingues was the only CBD athlete to compete for Brazil in 1936.
After his athletic career, Domingues sought a military career, eventually retiring with the rank of Brigadier General. He was state Secretary of Security during the merger of the states of Guanabara and Rio de Janeiro in 1975. He died without issue from respiratory failure, leaving his wife of 66 years, Sonia.
Personal Best\: 100 – 10.8 (1933).
