Final answer:
The character associated with organized crime and who helped Gatsby amass his wealth in The Great Gatsby is Meyer Wolfsheim. Wolfsheim's character reflects the 1920s' moral decay and Fitzgerald's themes of corruption behind the American Dream.
Step-by-step explanation:
The character in question from F. Scott Fitzgerald's The Great Gatsby is Meyer Wolfsheim. He is known as a notorious gambler who is rumored to have fixed the 1919 World Series, revealing the dark underworld that was part of the Jazz Age's glittering façade. Wolfsheim was instrumental in establishing Jay Gatsby's fortune, albeit through dubious and illicit activities. Readers are introduced to the character through the novel's narrator, Nick Carraway, who provides insight into the era's moral ambiguity and the complicated social relationships it fostered.The creation of Meyer Wolfsheim's character echoes Fitzgerald's broader theme of the illusion ARY nature of the American Dream and the moral decay hidden behind the veneer of wealth and prosperity in the 1920s. It also highlights Fitzgerald's keen social commentary on the era, reflecting a fascination with the lifestyles of the rich and the famous, as well as the dark and corruptive forces that enabled their opulence. This narrative fits within Fitzgerald's larger body of work, which often scrutinizes the tumultuous lives of society's elite during the Jazz Age.
