Who is Pumblechook, and how does he get Pip into Satis House?

Pumblechook is a character from Charles Dickens' novel "Great Expectations". He is a pompous, self-important bachelor who is a corn merchant, living in the market town of Rochester. Pumblechook is also Pip's uncle Joe's uncle, making him Pip's uncle-in-law.

Pumblechook gets Pip into Satis House through his acquaintance with Miss Havisham. Miss Havisham, a wealthy and eccentric woman, asks Pumblechook to find a boy to come and play at her house.

This visit changes the course of Pip's life as he meets Estella there and falls in love with her, and later becomes a gentleman with the help of a mysterious benefactor, whom he assumes to be Miss Havisham.
