Jay Gatsby - The title character and protagonist of the novel, Gatsby is a fabulously wealthy young man living in a Gothic mansion in West Egg. He is famous for the lavish parties he throws every Saturday night, but no one knows where he comes from, what he does, or how he made his fortune. As the novel progresses, Nick learns that Gatsby was born James Gatz on a farm in North Dakota; working for a millionaire made him dedicate his life to the achievement of wealth. When he met Daisy while training to be an officer in Louisville, he fell in love with her. Nick also learns that Gatsby made his fortune through criminal activity, as he was willing to do anything to gain the social position he thought necessary to win Daisy. Nick views Gatsby as a deeply flawed man, dishonest and vulgar, whose extraordinary optimism and power to transform his dreams into reality make him “great” nonetheless.
