History (pre-1970s)

Silicon Valley was born through the intersection of several contributing factors including a skilled science research base housed in area universities, plentiful venture capital, and steady U.S. Department of Defense spending. Stanford University leadership was especially important in the valley's early development. Together these elements formed the basis of its growth and success.

Military technology rootsedit

On August 23, 1899, the first ship-to-shore wireless telegraph message to be received in the US was from the San Francisco lightship outside the Golden Gate, signaling the return of the American fleet from the Philippines after their victory in the Spanish–American War in 1898. The ship had been outfitted with a wireless telegraph transmitter by a local newspaper, so that they could prepare a celebration on the return of the American sailors. Local historian Clyde Arbuckle states in Clyde Arbuckle's History of San Jose that "California first heard the click of a telegraph key on September 11, 1853. It marked completion of an enterprise begun by a couple of San Francisco Merchants' Exchange members named George Sweeney and Theodore E. Baugh…" He says, "In 1849, the gentleman established a wigwag telegraph station a top a high hill overlooking Portsmouth Squares for signaling arriving ships… The operator at the first station caught these signals by telescope and relayed them to the Merchant's Exchange for the waiting business community." Arbuckle points to the historic significance the Merchants Exchange Building (San Francisco) and Telegraph Hill, San Francisco when he goes on to say "The first station gave the name Telegraph to the hill on which it was located. It was known as the Inner Station; the second, as the Outer Station. Both used their primitive mode of communication until Messrs. Sweeney and Baugh connected the Outer Station directly with the Merchants's Exchange by electric telegraph Wire."

According to Arbuckle (p. 380–381) Sweeney and Baugh's line was strictly an intra-city, San Francisco-based service; that is until California State Telegraph Company enfranchised on May 3, 1852; whereas, O.E. Allen and C. Burnham led the way to "build a line from San Francisco to Marysville via San Jose, Stockton, and Sacramento". Delays to construction occurred until September 1853; but, "…San Jose became the first station on the line when the wire arrived here on October 15. The line was completed when James Gamble's northbound crew met a similar crew working southward from Marysville on October 24."

The Bay Area had long been a major site of United States Navy research and technology. In 1909, Charles Herrold started the first radio station in the United States with regularly scheduled programming in San Jose. Later that year, Stanford University graduate Cyril Elwell purchased the U.S. patents for Poulsen arc radio transmission technology and founded the Federal Telegraph Corporation (FTC) in Palo Alto. Over the next decade, the FTC created the world's first global radio communication system, and signed a contract with the Navy in 1912.

In 1933, Air Base Sunnyvale, California, was commissioned by the United States Government for use as a Naval Air Station (NAS) to house the airship USS Macon in Hangar One. The station was renamed NAS Moffett Field, and between 1933 and 1947, U.S. Navy blimps were based there. A number of technology firms had set up shop in the area around Moffett Field to serve the Navy. When the Navy gave up its airship ambitions and moved most of its west coast operations to San Diego, the National Advisory Committee for Aeronautics (NACA, forerunner of NASA) took over portions of Moffett Field for aeronautics research. Many of the original companies stayed, while new ones moved in. The immediate area was soon filled with aerospace firms, such as Lockheed, which was Silicon Valley's largest employer from the 1950s into 1980s.

Ham radio

The Bay Area was an early center of ham radio with about 10% of the operators in the United States. William Eitel, Jack McCullough, and Charles Litton, who together pioneered vacuum tube manufacturing in the Bay Area, were hobbyists with training in technology gained locally who participated in the development of shortwave radio by the ham radio hobby. High frequency, and especially, Very high frequency, VHF, transmission in the 10-meter band, required higher quality power tubes than were manufactured by the consortium of RCA, Western Electric, General Electric, Westinghouse which controlled vacuum tube manufacture. Litton, founder of Litton Industries, pioneered manufacturing techniques which resulted in the award of wartime contracts to manufacture transmitting tubes for radar to Eitel-McCullough, a San Bruno firm, which manufactured power-grid tubes for radio amateurs and aircraft radio equipment.

Welfare capitalism

A union organizing drive in 1939–1940 at Eitel-McCullough by the strong Bay Area labor movement was fought off by adoption of a strategy of welfare capitalism which included pensions and other generous benefits, profit sharing, and such extras as a medical clinic and a cafeteria. An atmosphere of cooperation and collaboration was established. Successes have been few and far between for union organizing drives by UE and others in subsequent years.

U.S. response to Sputnik

On October 4, 1957 the Soviet Union launched the first space satellite, Sputnik, which sparked fear that the Soviet Union was pulling ahead technologically. After President Eisenhower signed the National Aeronautics and Space Act (NASA), he turned to Fairchild Semiconductor,further explanation needed then the only company in the world that was able to make transistors. The president funded Fairchild's project,further explanation needed which was highly successful.

Stanford Universityedit

Stanford University, its affiliates, and graduates have played a major role in the development of this area. Some examples include the work of Lee De Forest with his invention of a pioneering vacuum tube called the Audion and the oscilloscopes of Hewlett-Packard.

A very powerful sense of regional solidarity accompanied the rise of Silicon Valley. From the 1890s, Stanford University's leaders saw its mission as service to the (American) West and shaped the school accordingly. At the same time, the perceived exploitation of the West at the hands of eastern interests fueled booster-like attempts to build self-sufficient local industry. Thus, regionalism helped align Stanford's interests with those of the area's high-tech firms for the first fifty years of Silicon Valley's development.

After World War II, Frederick Terman, as Stanford University's dean of the school of engineering, encouraged faculty and graduates to start their own companies. In 1951, Terman spearheaded the creation of Stanford Industrial Park (now Stanford Research Park, an area surrounding Page Mill Road, south west of El Camino Real and extending beyond Foothill Expressway to Arastradero Road), whereby the University leased portions of its land to high-tech firms. He is credited with nurturing companies like Hewlett-Packard, Varian Associates, Eastman Kodak, General Electric, Lockheed Corporation, and other high-tech firms, until what would become Silicon Valley grew up around the Stanford University campus.

In 1956, William Shockley, the co-inventor of the first working transistor (with John Bardeen and Walter Houser Brattain), moved from New Jersey to Mountain View, California, to start Shockley Semiconductor Laboratory to live closer to his ailing mother in Palo Alto. Shockley's work served as the basis for many electronic developments for decades. Both Fredrick Terman and William Shockley are often called "the father of Silicon Valley".

During 1955–1985, solid state technology research and development at Stanford University followed three waves of industrial innovation made possible by support from private corporations, mainly Bell Telephone Laboratories, Shockley Semiconductor, Fairchild Semiconductor, and Xerox PARC. In 1969, the Stanford Research Institute (now SRI International), operated one of the four original nodes that comprised ARPANET, predecessor to the Internet.

Stanford Industrial Park

After World War II, universities were experiencing enormous demand due to returning students. To address the financial demands of Stanford's growth requirements, and to provide local employment opportunities for graduating students, Frederick Terman proposed the leasing of Stanford's lands for use as an office park, named the Stanford Industrial Park (later Stanford Research Park) in the year 1951. Leases were limited to high technology companies. Its first tenant was Varian Associates, founded by Stanford alumni in the 1930s to build military radar components. However, Terman also found venture capital for civilian technology start-ups. One of the major success stories was Hewlett-Packard. Founded in Packard's garage by Stanford graduates Bill Hewlett and David Packard, Hewlett-Packard moved its offices into the Stanford Research Park shortly after 1953. In 1954, Stanford created the Honors Cooperative Program to allow full-time employees of the companies to pursue graduate degrees from the University on a part-time basis. The initial companies signed five-year agreements in which they would pay double the tuition for each student in order to cover the costs. Hewlett-Packard has become the largest personal computer manufacturer in the world, and transformed the home printing market when it released the first thermal drop-on-demand ink jet printer in 1984. Other early tenants included Eastman Kodak, General Electric, and Lockheed.

Silicon transistorsedit

Up until the late 1950s, germanium was the dominant semiconductor material for transistors and other semiconductor devices. Germanium was initially considered the more effective semiconductor material, as it was able to demonstrate better performance due to higher carrier mobility. The relative lack of performance in early silicon semiconductors was due to electrical conductivity being limited by unstable quantum surface states, preventing electricity from reliably penetrating the surface to reach the semiconducting silicon layer.

In 1953, William Shockley left Bell Labs in a disagreement over the handling of the invention of the bipolar transistor. After returning to California Institute of Technology for a short while, Shockley moved to Mountain View, California, in 1956, and founded Shockley Semiconductor Laboratory. Unlike many other researchers who used germanium as the semiconductor material, Shockley believed that silicon was the better material for making transistors. Shockley intended to replace the current transistor with a new three-element design (today known as the Shockley diode), but the design was considerably more difficult to build than the "simple" transistor. In 1957, Shockley decided to end research on the silicon transistor. As a result of Shockley's abusive management style, eight engineers left the company to form Fairchild Semiconductor; Shockley referred to them as the "traitorous eight". Two of the original employees of Fairchild Semiconductor, Robert Noyce and Gordon Moore, would go on to found Intel.

In 1957, Mohamed Atalla at Bell Labs developed the process of silicon surface passivation by thermal oxidation, which electrically stabilized silicon surfaces and reduced the concentration of electronic states at the surface. This enabled silicon to surpass the conductivity and performance of germanium, leading to silicon replacing germanium as the dominant semiconductor material, and paving the way for the mass-production of silicon semiconductor devices. This led to Atalla inventing the MOSFET (metal-oxide-silicon field-effect transistor), also known as the MOS transistor, with his colleague Dawon Kahng in 1959. It was the first truly compact transistor that could be miniaturised and mass-produced for a wide range of uses, and is credited with starting the silicon revolution.

The MOSFET was initially overlooked and ignored by Bell Labs in favour of bipolar transistors, which led to Atalla resigning from Bell Labs and joining Hewlett-Packard in 1961. However, the MOSFET generated significant interest at RCA and Fairchild Semiconductor. In late 1960, Karl Zaininger and Charles Meuller fabricated a MOSFET at RCA, and Chih-Tang Sah built an MOS-controlled tetrode at Fairchild. MOS devices were later commercialized by General Microelectronics and Fairchild in 1964. The development of MOS technology became the focus of startup companies in California, such as Fairchild and Intel, fuelling the technological and economic growth of what would later be called Silicon Valley.

Computer networkingedit

On April 23, 1963, J.C.R. Licklider, the first director of the Information Processing Techniques Office (IPTO) at The Pentagon's ARPA issued an office memorandum addressed to Members and Affiliates of the Intergalactic Computer Network. It rescheduled a meeting in Palo Alto regarding his vision of a computer network, which he imagined as an electronic commons open to all, the main and essential medium of informational interaction for governments, institutions, corporations, and individuals. As head of IPTO from 1962 to 1964, "Licklider initiated three of the most important developments in information technology: the creation of computer science departments at several major universities, time-sharing, and networking." By the late 1960s, his promotion of the concept had inspired a primitive version of his vision called ARPANET, which expanded into a network of networks in the 1970s that became the Internet.

Immigration reformedit

The Immigration and Nationality Act of 1965 and other factors such as the mass exodus by Vietnamese boat people resulted in significant immigration, particularly by Asians, Latinos, and Portuguese, to Silicon Valley where they contributed to both the high-tech and production workforce. The Asian-American population in Santa Clara County rose from 43,000 in 1970 to 430,000 in 2000. During the same period the Latino population grew to 24% in the county and 30% in San Jose. The African-American population in the county remained steady but grew slightly to about 5%. Expansion of the H-1B visa in 1990 also played a role.
