Apolonio Castillo
Apolonio Castillo Díaz was born in Tecpán de Galeana, Guerrero and died in Acapulco. Was a Mexican swimmer who competed in the 1948 Summer Olympics and 1952 Summer Olympics in butterfly stroke.
Castillo was a close friend of Ramón Bravo, he taught to the world famous photographer and underwater filmmaker to dive.
This great athlete died in Acapulco, at the age of 35, after making several dives in the waters of the bay trying to rescue the bodies of Joseph Arthur Mitchel and Edith Hallock, two elder Americans tourists who were victimized by the Texan Rudy Fenton Cavalzono and the boatman Daniel Ríos Ozuna days before in the bay of Acapulco and whose approximate depth is 200 feet. In the last search Castillo floated but suffered a decompression accident and three days later he was taken to the hyperbaric chamber of the Naval Base, where at dawn on March 11, 1957 the great Polo Castillo ceased to exist.
