Salvatore Maranzano
After Monastero's murder Giuseppe Siragusa became the new boss of the Pittsburgh family. Siragusa emigrated in 1910 from Sicily to Brooklyn and later to Pittsburgh, where he manufactured and traded in illegal alcohol in Allegheny County. He became known as the “Yeast Baron” after becoming the largest supplier of yeast to illegal beermakers. Siragusa was a close ally to the Castellammarese Clan in New York City and paid tribute to Salvatore Maranzano. On September 13, 1931, Siragusa was murdered in his Squirrel Hill home, just days after Salvatore Maranzano was murdered.
