The Atlas E-2 Space Booster, or launch vehicle, is a modified intercontinental ballistic missile developed by the Convair Division of General Dynamics and the U.S. Air Force. The basic concept of the Atlas system was proven in its first flight on June 11, 1957, followed over the years by the launching more than five hundred vehicles including the Pioneer, Ranger, Mariner, and Surveyor. Many payloads were sent into orbit as detachable sections of Atlas missiles.

With its landscaped embankments, limited access, and depressed roadway, Arroyo Seco Parkway (now known as the Pasadena Freeway) became the prototype of the Los Angeles freeway system. Motorists enjoy a scenic drive featuring landscaped embankments lush with native chaparral. The curving alignment traverses a chain of small parks shaded by sycamores and eucalyptus and exposed views of the snow-capped San Gabriel Mountains.

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 articulated wheel-base steam locomotive represents the final phase of steam locomotive development in size and power. The cab-in-front feature was widely used by the Southern Pacific Railroad beginning in 1909 to alleviate smoke and heat problems for locomotive personnel en route through tunnels and snow sheds. This locomotive, built by the Baldwin Locomotive Works, operated between 1944 and 1956 before being displaced by a diesel-electric locomotive.

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.
