Charles Pollock was a graduate of the Pratt Institute and a contemporary of fellow designer George Nelson. He created a portfolio of designs and presented them to Florence Knoll. His winning piece, after much re-working of various designs for Knoll, was his unique executive Pollock Chair which used an aluminum “rim,” which outlined the chair as the main structural and design element. This rim would hold the parts together, without any further support. Slots in the aluminum held the back shell and the upholstery in place, and the plastic back became rigid only after being fitted into the frame. The resulting design was an achievement in structure and aesthetics, and the chair remains a Knoll classic to this day.
