1950-1959

The IBM 350 disk drive storage development led to the breakthrough of on-line computer systems by providing the first storage device with random access to large volumes of data. Since its introduction on September 4, 1956, it has become the primary computer bulk-storage medium, displacing punched cards and magnetic tapes and making possible the use of the computer in such areas as airline reservations, automated banking, medical diagnosis, and space flights.

The integration of pump and turbine was the first of many to be installed in power-plant systems in the United States. It was the largest and most powerful in the world. As a "pump storage" unit in the Tennessee Valley Authority's system, it effected significant economies in the generation of electrical energy. The unit was designed by engineers of the Tennessee Valley Authority and the Allis-Chalmers Company. It was built by Allis-Chalmers.

Founded in 1957, Raychem Corporation was the first company to successfully apply the new science of radiation chemistry to commercial use. This accomplishment led to the creation of tough new materials and high-performance products such as irradiated polyethylene insulated wire and heat-shrinkable tubing through the crosslinking of polymeric materials.
