Bruce Hanna was born in 1941. After graduating from Pratt Institute in 1963, he embarked on a career focused on using modern technology and materials to create efficient and practical products. Hanna worked as a creative partner with Andrew Morrison, with whom he introduced several innovative products for the Knoll company in the 1970s. Through their exploration of the possible applications of aluminum in modern furniture, the couple introduced a lounge seating system in 1971, followed a year later by a related line of tables, and in 1974 by a collection of office chairs. In 1976, Hanna founded his own studio, where he created numerous projects, including the "Hannah Desk System" for Knoll, chosen in 1990 by the Industrial Designers Society of America as "Design of the Decade". This innovative design includes the use of storage "pedestals" to support the countertop, a concept that eliminated the need for a frame, increasing flexibility and reducing costs. Since 1993, Bruce Hanna has taught at Pratt Institute.
