Paul Cook begins the interview with a discussion of his family background and childhood. When Cook was young, he took an interest in chemistry, developing a laboratory in the basement of his parents' house. After graduating from high school in 1941, he attended the Massachusetts Institute of Technology (MIT), where he studied chemical engineering with Warren K. Lewis. In 1943, after enlisting in the Army, he went to basic infantry training. Cook then enrolled in the Army Specialized Training Program (ASTP), through which he attended Stanford University for two terms, studying mechanical engineering. After a year, Cook was sent to the Hunter Liggett Military Reservation, and then to Fort Benning, where he became an MP. While at Fort Benning, he joined the Officer Candidate School, and shortly after completing the training, was sent to fight in Italy. In February 1946, Cook left the Army and worked for Submarine Signal in Boston. He then returned to MIT, where he completed his degree in 1947. After graduation, Cook started the Warren Wire Company with his older brother. A year later, Cook left the fledgling company to join the Stanford Research Institute as a chemical engineer. There he worked on a number of projects, including the growth of the algae Chlorella and the potential uses of waste fission products. In 1951, Cook founded the Sequoia Process Corporation. Five years later, he left Sequoia to found Raychem Corporation, which opened in 1957. Cook concludes the interview with a discussion of Raychem's international competition, the growth of the company, his thoughts on managing innovation, and the possibilities of radiation technology.
