To Prohibition-era gangsters, history buffs and true crime aficionados, he was Meyer Lansky, the financial mastermind who built an international gambling empire. To his namesake, he was simply "grandpa."
Meyer Lansky II, the grandson of the late mob boss who helped establish organized crime across the nation, reflects on his grandfather through personal letters, photographs and firsthand memories in his new book with S. J. Peddie, "The Lansky Legacy: The Life and Letters of Meyer Lansky."
"He never mentioned the names of anybody that he worked with. He was always cautious with that," Lansky told Fox News Digital.

Growing up in Washington state, the younger Lansky initially saw his grandfather as a stern, serious figure who strictly compartmentalized his life. The elder Lansky never brought up his underworld dealings; instead, he focused on teaching his grandson how to present himself to the world, introducing him to fine details like tie pins and shoehorns.
"Growing up in Washington state, I wasn't exposed to those kinds of things anywhere else," Lansky said. "He was always asking me about my grades, my studies and what books I was reading.
"He'd give me basic advice: 'Whatever you do, do a good job. Be honest with people, provide good service and people will come back to you.'"

The elder Lansky, widely dubbed the "mob's accountant," rose to prominence in the early 20th century alongside childhood friends Benjamin "Bugsy" Siegel and Charles "Lucky" Luciano. Together, they revolutionized organized crime, building lucrative gambling operations from Havana to Las Vegas.
"He was right alongside Luciano and Bugsy Siegel during the transformation of the syndicate into the modern American Mafia," Lansky said.
That reputation carried real-world danger. The younger Lansky recalled a chilling incident from his childhood, when his grandfather's notoriety and perceived wealth nearly led to his kidnapping.
As he grew older, the veil began to slip.

"One day I was listening to the radio and heard that Treasury Secretary John Connally was going to Las Vegas to investigate Meyer Lansky," he said, referencing the decades-long, unsuccessful federal effort to convict his grandfather.
"When my grandfather visited a week later, I told him, 'Hey, I heard your name on the radio.' He looked at me, smiled, and said, 'You did?' He didn't elaborate, but I knew at that point he realized I was going to figure out who he really was."

While mob historians contend that the Polish-born gangster perfected modern money laundering and amassed vast fortunes, a central mystery remains: What happened to the money?
If the elder Lansky stashed away millions, his grandson noted, the family never saw it.
Yet, the physical legacy remains impossible to ignore.

"He was heavily involved in transforming the American Mafia into something that still holds an irresistible, nostalgic grip on culture," Lansky said. "These guys are major figures of history.
"They took a barren desert and turned it into a sophisticated gambling empire."
