I do believe Luciano was the most powerful and influential Boss of all time but no one person can account for everything
Luciano deserves that accolade because he ordered the assassination of the two Moustache Petes--Masseria and Maranzano--and formed the Commission. He put the modern Mafia on a businesslike footing. He also had the wisdom not to declare himself
capo di tutti capi--he was that secure in his own mind.
The question to me is, Who made who? Luciano or Lansky?
Luciano and Lasky were best friends since their teens. Meyer was Charlie's most trusted adviser, and he arranged the murders of Masseria and Maranzano. He also advised the Commission, collectively and individually. But, the two were not inseparable, and went their separate ways at times. I'd say neither made the other, but they were a powerful team when they worked together..
