Referred to as ‘Good-looking Harry,’ he was a co-employee and a bank-robbing mentor of John Dillinger. He fulfilled Dillinger when the last mentioned portion a 10-20 season word for robbery, and Pierpont had been a hard legal with an extended rap sheet. He trained Dillinger to become methodical about robberies: preparing the robberies, casing the joint, and organizing – even exercising – the getaway routes. He was created in Muncie, Indiana. He was performed by Geoffrey Lewis in the 1973 film Dillinger.
