Achille Porcasi was born in Palermo, Sicily. His father’s name was also that of a Greek hero, Hercules Porcasi. He was a graduate of the conservatory in Naples. He first came to the United States in the late 1890s where he conducted an Italian band in Buffalo. Later he moved to St. Louis. He married Nellie Wilcox (*1885) from Michigan on 3 September 1913, probably his second wife, and they later settled in California, where Achille Porcasi died in Los Angeles in 1941. It was suspected that he was not legally divorced from his Italian wife at the time of his second marriage.
