Dan Cody

Gatsby worked on Lake Superior the next summer fishing for salmon and digging for clams. One day, he saw a yacht owned by Dan Codywho is a wealthy copper mogul, he rodeout to warn him about an impending storm. Cody was grateful and took young Gatz, who gave his name as Jay Gatsby, on board his yacht as his personal assistant. Traveling with Cody to the Barbary Coast and the West Indies, Gatsby fell in love with wealth and luxury. Cody was a heavy drinker, and one of Gatsby’s duties was to look after him during his drunken "celebration". This gave Gatsby a healthy respect for the dangers of alcohol and convinced him not to become a drinker himself. When Cody died, he left Gatsby $25,000, but Cody’s mistress prevented him from claiming his inheritance. Gatsby then dedicated himself to becoming a wealthy and successful man.
Gatsby got "scammed" out of his inheritance. Coming home from World War I, Gatsby is broke, owning only the clothes on his back, his uniform. He is starving, when he meets Wolfsheim in a pool hall. Wolfsheim is a gangster. He puts Gatsby to work in his criminal activities. Gatsby becomes enormously rich very quickly, but his life is not respectable. He becomes corrupt through his association with Wolfsheim.
