How old was salvador Dali's brother when he died?

Salvador Dalí had a brother named Salvador Dalí i Cusi, who died nine months before Dalí was born. As a result, he never had the opportunity to meet his brother, and the loss had a lasting impact on Dalí throughout his life. Since he died at a very young age, he was not alive long enough to have an age at the time of his death in the conventional sense.
