A-8 was Thomas “Tommy the Bull” Pennachio (Genovese)
Pennachio dates back to the days of boss Lucky Luciano himself. In fact, he later got indicted along with the boss and others for operating the infamous city-wide prostitution racket that later sent Lucky up-the-river for conspiracy. Tommy the Bull was said to have helped soldier "Little Davy" Petillo oversee, control, and subsequently extort New York’s various whore houses on behalf of Luciano and the mob.
