Harold Finch

Harold Finch is the main protagonist in Person of Interest.  
He is portrayed by , who also portrayed Benjamin Linus in Lost.
== Overview ==
Harold was a reclusive billionaire that created a computer software that inserts social security numbers that can tell who is a victim or criminal.  It was after 9/11 attack he and his partner Nathan Ingram created an artificially intelligent machine that could predict terrorist attacks through processing government feeds from email, phone calls and surveillance cameras.  The machine also generated a list of predicted murders and violent crimes "non relevant to national security. It was determined that this non-relevant list should have to be ignored, since passing the information to law enforcement could reveal the existence and extent of constitutionally proscribed government surveillance.  For this reason, and rationalizing it as done for the greater good, Finch programmed the machine to delete the non-relevant list every day at midnight. Ingram and Finch clashed when Finch discovered that Ingram had created a backdoor into the machine before handing it over and was trying to warn and even save people on the "irrelevant list." Finch shut down the backdoor. At the secret library location where Ingram had created his backdoor to the machine, Finch reactivated the backdoor and begin his own mission to save non-relavant numbers.  Harold Finch recruited John Reese to help him with his war on crime. 
==Personality==
Finch is a reclusive, security-conscious and intensely private billionaire software engineer. His real name is unknown (beyond the fact that his first name really is Harold) and he has many aliases (most commonly Harold Wren), using various species of birds as the last name. Finch has developed a machine that can isolate the Social Security numbers of people with either premeditated homicidal intent or who will be homicide victims, based on its analysis of surveillance data — aside from its primary purpose of detecting potential national security threats. Following a traumatic event in his own life that led to the death of his business partner and close friend, Nathan Ingram, he recruits Reese to help him deal with the people the Machine identifies. Finch lives and works in an abandoned library and shows the results of severe physical injuries, including the inability to turn his head, a rigid posture, and a limp.
