What is the name of the convict in Great Expectations?

The Convict in Charles Dickens’ novel Great Expectations is one of the more colorful characters in the story. His relationship with Pip forms one of the core plot-lines of the Great Expectations.
The first line uttered in the churchyard by the Convict in Chapter I is a memorable piece of characterization. When the Convict confronts a crying Pip, he snarls,

“Hold your noise . . . Keep still, you little devil, or I'll cut your throat!''

Despite this rough appearance and callous demeanor, the Convict is not entirely evil; his backstory is revealed through the remainder of the novel. The Convict is Abel Magwitch, a lifelong criminal. Magwitch's earliest memory is stealing turnips from a garden, and he is convicted for counterfeiting and attempted murder. He is sent to Australia for a life sentence but works hard and becomes wealthy. Upon returning to England years later, Magwitch determines to make up for his criminal past by taking Pip under his wing and becoming a father figure to the young man.
