Dalitz has long been credited as the "founder" of Vegas. I think a lot of people took the Warren Beatty movie ('Bugsy) as gospel, not knowing the real story. I believe the Moe Greene character in GF1 was a loosely veiled reference to Dalitz. Also Hyman Roths "I didn't ask...who gave the order" soliloquy in GF2 clearly refers to Dalitz. Actually,I think the biggest Vegas gangster of all is Oscar Goodman (LOL)
