Lippincott joined Pratt Institute's faculty in 1936, collaborating with Donald Dohner to help establish its design education program.[3] While teaching, Lippincott began consulting as an industrial designer and authored Economics of Design in 1937.[3]
In 1943, Lippincott and Dohner opened a design office in New York, initially partnering with the Douglas T. Sterling Company in Stamford, CT, and named the firm Dohner & Lippincott.[3] After Dohner's death, Lippincott took over the editing of the industrial design section of Interiors magazine.[3] The firm was renamed J. Gordon Lippincott and Company in 1944. Walter Margulies joined the firm in 1944, and it was subsequently renamed as Lippincott & Margulies.[3] The firm's notable projects include the 1946 redesign of Campbell's soup packaging, introducing the iconic red-and-white can.[4]
Lippincott published another book, Design for Business, in 1947 through Paul Theobold.[3] He retired in 1969.[3]
