Although Torromé qualified to represent Great Britain at the 1908 Summer Olympics, he opted to compete for his father's home country and so became the only representative for Argentina at the 1908 Summer Olympics held in London. He scored 228.9 points in the men's individual competition, placing last of the seven skaters who finished competition.[5] Torromé also served as a judge for the pairs competition at the same Games.[6] He would continue to be an active judge and was a part of the judging team for the 1912 World Figure Skating Championships.[2]
From 1881, Torromé was a partner in his father's Commissioned Merchants business in Laurence Pountney Lane, Candlewick, London. His father retired in 1903 and left the business to be run by Horatio and his brother Franco. Torromé was also known for being an artist.[7]
Horatio Torromé died on 16 September 1920 in Willesden, London.[2]
