After arriving in Las Vegas in 1968, Rosenthal launched a betting parlor. Wiretapped by the FBI, he was indicted on federal bookmaking charges, but a judge threw the case out on a technicality.
In 1969, Rosenthal had married Geri McGee, a statuesque blond and former topless showgirl, with whom he had two children.
The couple later divorced, after she had an affair with Rosenthal's Chicago boyhood friend, Anthony "Tony the Ant" Spilotro, who had moved to Vegas.
At the urging of his wife, Rosenthal got a job in a casino.
He was working as a floor manager at the Stardust Hotel and Casino in 1974 -- "The only guy below me was the shoeshine man," he later said -- when he was appointed to a $250,000-a-year executive position with Argent Corp., which owned or controlled the Stardust, Hacienda, Fremont and Marina hotel-casinos.
But in 1976, the state Gaming Commission ruled that Rosenthal was unsuitable for licensing to run casinos, partly on grounds of alleged organized crime associations.
Rosenthal always denied any charges of mob involvement or skimming profits from the casinos he managed.
"No one put me anywhere," he told the Palm Beach Post in 1995, "and I'm not the least bit concerned or amused that some think otherwise. No one controls Frank Rosenthal. Underline that. No one controls Frank Rosenthal."
On the evening of Oct. 4, 1982, Rosenthal had just finished dining at a Tony Roma's restaurant in Las Vegas when he got into his Cadillac Eldorado. When he turned on the ignition, a bomb under the gas tank exploded.
An unnamed law enforcement source told the Las Vegas Review-Journal at the time that Rosenthal had apparently started the car with the door still open.
"It blew him out of the car," the source said. "It's probably the thing that saved his life."
Rosenthal suffered minor burns on his face and legs.
Authorities had warned him a year earlier, the source said, that his life was in danger and that they had heard of plots to kill him.
After the attempt on his life, Rosenthal moved with his children to California and then to Florida. In 1988, the Nevada Gaming Commission listed him in the state's "Black Book" of people barred from casinos.
Rosenthal's life story was told in Nicholas Pileggi's nonfiction book "Casino," which inspired director Martin Scorsese's 1995 movie of the same name, starring Robert DeNiro as Sam "Ace" Rothstein, Sharon Stone as his wife and Joe Pesci as his mobster pal.
When the book and movie came out, Rosenthal was managing his nephew's bar and grill in Boca Raton, Fla., where he had moved in 1987.
"Let me tell you this," Rosenthal said of the movie, "I'm not Bob and he's not Frank."
In Florida, he also ran a sports betting website and served as a consultant for offshore casinos.
Born June 12, 1929, in Chicago, Rosenthal early on became a professional gambler who bet on football, basketball, baseball and boxing.
"You like something and you get into it," he told the Sun-Sentinel in 1994.
"I was studying all phases of gambling in my late teens. It's no different than anything else, like a doctor, a lawyer or a writer."
