According to Cohen, Rothstein was the 'Moses of Jewish gangsters', a rich man's son, who showed the young and uneducated hoodlums of the Bowery how to have style. Lucky Luciano, who would become a prominent boss within the Italian-American Mafia and organize New York's Five Families, once claimed that Arnold Rothstein "taught me how to dress". The stereotypical attire of the American mobster portrayed in movies can partially trace its roots directly to Rothstein.[2][20][page needed]
