Who is Bart Pollock from Revolutionary Road and what is their importance?

Bart Pollock is the head of the Akron sales office for Knox Business Machines. A large, burly midwesterner, he presses Frank Wheeler to complete a brochure he's requested, and then becomes so enamored with the result that he comes to the home office in New York to meet with Frank's boss. Pollock envisions a whole series of sales brochures in the same style that would prove useful in making the transition to the computer age (in 1955). This endorsement eventually leads to an offer of a bigger job with more responsibility and more pay.
