Who are the Buchanans?

Daisy Buchanan

Daisy is Nick's cousin, Tom's wife, and the woman that Gatsby loves. She had promised to wait for Jay Gatsby until the end of the war, but after meeting Tom Buchanan and comparing his extreme wealth to Gatsby's poverty, she broke her promise. Daisy uses her frailty as an excuse for her extreme immaturity.

Tom Buchanan

A brutal, hulking man, Tom Buchanan is a former Yale football player who, like Daisy, comes from an immensely wealthy Midwestern family. His racism and sexism are symptomatic of his deep insecurity about his elevated social position. Tom is a vicious bully, physically menacing both his wife and his mistress. He is a thoroughgoing hypocrite as well: though he condemns his wife for her infidelity, he has no qualms about carrying on an affair himself.
