Classic Silicon Valley: 1976
Homebrew Computer Club (hobbyists)– 6502 Processor Design-around Motorola 6800 Cheap (1/6th the price) Hobbyist-level device
– Steve Jobs and Steve Wozniak
– The Apple I (to sell to friends)
1975, MP; Gordon French garage; O
Classic Silicon Valley: 1976
Wozniak-Jobs partnership – called it “Apple Computer Company”– Started in a garage in Los Altos– Sold 200 or so; attracted attention of
investors– IPO in 1980: 2nd-largest IPO since Ford
Motor Company 25 years before – Now largest stock market capitalization
How could this happen? Why in the SF Bay Area?

Before 1920
This was more typical …
Let’s Go Back …Federal Telegraph– Formed in 1909 in
Palo Alto (by a Stanford grad)
– Lee de Forest invented the audion oscillator and amplifier in 1907
– Pioneered continuous-wave radio
– Sold equipment to US Navy in World War I

Let’s Go Back …
1st commercial radio broadcast– Charles “Doc” Herrold Early Stanford EE grad Started an SF firm
– Destroyed in the 1906 earthquake/fire
Then started a San Jose school nearSJSU to teach radio arts (1909)
– First Commercial broadcast, San Jose, 1909
voice and music: “San Jose Calling”
– FN, then SJN, then KQW, becomes KCBS740 AM, 106.9 FM
Clear-Channel;Music til Dawn
Near Fairmont;Audio in 1910
Early Roots …
Otis Moorhead– Early Stanford EE grad– Radio amateur & vacuum tube
entrepreneur– Established Moorhead Laboratories A vacuum tube firm Set up in San Francisco in 1917
– Moorhead manufactured “bootleg” receiving tubes for radio sets
– A patent-infringement lawsuit put him out of business in the early 1920s.

William Eitel
Took shop class at Los Gatos High SchoolWorked in his father’s quarry – ass’t blacksmith, machine operatorVisited shops of Hall-Scott Motor Car Co.– Operation of Complex machinery
William Eitel, W6UF1908 - 1989
Jack McCullough, Charles Litton
Attended California School of Mechanical ArtsNow Lick-Wilmerding High School, San Francisco (private)
Founded in S.F. by James Lick, $540,000Opened in 1895; free education for boys, girlsOne of the best West Coast technical hi schools– Rigorous training in the mechanical trades – Many became excellent machinists– Gained "a realistic 'feel' of materials and
processes” [Litton]

Jack McCullough, Charles Litton
McCullough continued at a local junior collegeLitton enrolled in Stanford's ME dept:– Curriculum with strong practical flavor– Courses in shop work & administration,
machine drawing & design, power plant engineering, chemistry courses
– BS-ME in 1924
Eitel, Litton, and McCullough
Introduced to amateur “ham” radiothrough their families and friends in 1910’s, ’20’s – Became acquainted with the technology of
power tubes through activities in ham radio– Bay Area had 1,200 licensed amateurs 10 percent US total

Ham Radio in SF Bay AreaIsolated and peripheral region– A continent away from urban and industrial centers– But a large and vibrant ham radio community
Geographical and cultural factors: – Strong maritime orientation– SF was one of the largest seaports on the West
Coast of USA– Several military bases; US Navy presence – Commercial shipping firms relied on radio comm’n– Considerable visibility for technology in 1900s ’10’s– Navy, shipping companies employed radio
operators, many of whom were involved in amateur radio
Ham Radio in SF Bay AreaActive center of radio mfg in the 1910s, ‘20sElectronics firms:– Remler - made radio sets
– Magnavox - leading manufacturer of loudspeakers
– Heintz and Kaufman Designed custom radio equipment
– Federal Telegraph One of the earliest radio companies in the US Produced radio transmitters in the 1910s.
These firms made radio parts available to local hobbyists, and hired radio amateurs

Ham Radio Subculture
Camaraderie and intense sociability– A way to make friends– Communicating "over the air," face to face in clubs
Egalitarianism and a democratic ideology– little heed to distinctions of class,
education– Santa Clara County radio club, which Eitel
chaired in the mid 1920s, had “farm boys, Stanford students, Federal Telegraph technicians, and retired executives”
Ham Radio Subculture
Representatives of the citizenry– Opposed to large companies, patent
monopolies, undemocratic organizations
Interest in extending radio technology– Built reputations: innovating new circuitry,
devising clever transmitters, contacts with faraway lands
Mix of competitiveness and collaboration A lot like Home Brew Computer Club, and today’s Silicon Valley …

Following our Heroes …
Eitel, Litton, McCullough, ham friends– Learned about vacuum tubes– Built their own equipment, parts– Made notable contributions – 1924: Litton and Stanford radio club made
first contact with Australia and New Zealand
– 1928: Eitel pioneered 10-meter waves (30 MHz) for transcontinental communication
– Opened VHF bands to radio communication
The Tube Business
General Electric, Westinghouse, AT&T– All East Coast companies– Developed hi-power transmitting tubes in
early 1920s – Difficulties in producing consistent, reliable – Required precise machining, glass blowing
(Pyrex)– Exotic materials, sophisticated sealing
techniques
“The Origins of Silicon Valley”For Int’l Wafer Level Packaging Conference
November 6, 2013
11
Following our Heroes …
Litton got local job through ham friend– Research at Federal Telegraph– Built to 60 engineers and scientists – Became sole supplier of radios to IT&TEitel got local job through ham friend– Mechanic at Heintz and Kaufman Inc Heintz was a ham; focus on HF radio equipment
– Recruited McCullough a year later
The Tube Business in the ’20sCould not buy transmitting tubes on open market– RCA, GE, Western Electric, and Westinghouse Exclusive cross-licensing of 2000 patents
– RCA set up by GE, US Navy to ensure US dominance
– Sole producers/distributors of power-grid tubes Refused sale to Federal Telegraph,
Heintz & Kaufman– Threats to RCA’s domination
So both companies developed triodes– Litton and Eitel headed their tube shops
“The Origins of Silicon Valley”For Int’l Wafer Level Packaging Conference
November 6, 2013
12
Tube Shops’ Challenge
Design around ~250 RCA patents– Enormously difficult task (Samsung vs Apple case)
– RCA had shut down Sylvania’s tube businessHired locally (many hams); got resources from IT&T (French engineers)–Eitel, Litton collaborated with each other
(novel!)
–Based on friendships over the years–Didn’t compete with other’s marketWorked closely with patent attorneys
Tube Shops’ ChallengesHeintz, Eitel, and McCullough engineered a rugged new power tube: – New materials, manufacturing methods– Tube’s plates of tantalum (avoid patents)– New shock-resistant seals – Create high vacuums (> reliability)More reliable, longer life than RCA’s tubesDidn’t infringe RCA’s patents
“The Origins of Silicon Valley”For Int’l Wafer Level Packaging Conference
November 6, 2013
13
Tube Shops’ ChallengeLitton invented the glass lathe – For assembly, glass blowing, and sealing– Make complex tubes in large quantities– Allowed high repeatability, precision Built tube shop on parents' property
The Ham Radio Market
Heintz and Kauffman 354 Power Triode Tube

November 6, 2013
14
The US Depression Formed Eitel-McCullough Inc (Eimac)– To build high-power, high-frequency tubesFinancing: – Harrison: real-estate agent in San Bruno– Preddey: ran movie theaters in San
Francisco– Eitel and McCullough
brought their know-how – Profits to be shared
Precursor to today’s Menlo Park Venture-Capital Firms
The US DepressionLitton, Eitel, McCullough cooperated closely– Litton helped set up vacuum tube shop– Gave castings, engineering blueprints for lathe– Freely exchanged technical, commercial
information – Reduced risks, for the two small tube-
related businesses
Like Jobs & Wozniak, Homebrew Computer Club
“The Origins of Silicon Valley”For Int’l Wafer Level Packaging Conference
November 6, 2013
15
The US Depression
1936: Frederick Terman asked Litton to join Stanford EE department as lecturer– Shared knowledge with staff, students– Litton $1000 grant: let Terman bring
Packard to campus for grad studies, work with Litton, Hewlett, others
Start of University/Industry cooperation
Threats to Peace Growing threats from Japan and Germany– President Roosevelt rebuilt the Army, Navy– New electronic system: radio detection
and ranging (radar)Needed high-voltage transmitting tubes – Only Eimac’s best tubes worked at the
high voltages and frequencies

November 6, 2013
16
The Klystron
Russell and Sigurd Varian developed the klystron in 1937– Russell went to Stanford, then worked at
Farnsworth’s Television Laboratory in SF– Philo Farnsworth pioneered TV in 1920’sThey worried about Germany– Hoped to use microwaves to detect planes– 1937: Moved to Stanford’s labs to work
with HansenUsed Litton’s free adviceUsed Hansen’s theoretical assistance
The Klystron – PA Times, Jan. 30, 1939

17
Pre-War Expansion
RCA, Western Electric selected for producing Eimac’s best tubes– NRL helped Eimac get sub-contracts– Bank of America financing, volume
productionManagerial techniques to thwart unions, keep employees happy, productive– Profit-sharing, cafeteria, medical clinic
Similar to Hewlett-Packard, Fairchild, Intel, Tandem …
Post-War Realignment RCA, others focused on TV, broadcastEimac developed new line of better tubes– Power tetrodes for high frequencies– FCC’s surprise shift of FM radio to VHF– RCA, others’ tubes wouldn’t work at VHF– RCA copied Eimac’s tubes, which did work
“The Origins of Silicon Valley”For Int’l Wafer Level Packaging Conference
November 6, 2013
18
Reversal of Fortunes
In 1947, Eimac sued RCA and GE– alleging patent infringement on tetrode– GE, RCA lost the lawsuit, halted
production – Eimac transformed them into its own
sales force and distribution network– Let them buy Eimac products and resell
them under their own names
The “Big Dog” was now Silicon Valley!
Charles Litton After the War
Focus on higher-power klystrons– For physics research, linear accelerators– Scaled from 30 kilowatts to 30 megawatts– Transformed Stanford into a major player
– Developed “Recipe" to build a firm: little initial capital; R&D contracts; engineering teams and a product line; move to production
“The Origins of Silicon Valley”For Int’l Wafer Level Packaging Conference

19
Varian Associates
1948: Russell and Sigurd Varian, Edward Ginzton, Myrl Stearns, Frederick Salisbury, Donald Snow (Russell, Edward, Myrl: Stanford)
– Families of modest means, progressive politics– Worker control and share in ownership– Small cooperative-like laboratory closely
linked to university research – Several small defense contracts (Litton
recommended)– From GE: specialty klystron for new UHF TV
(while GE worked on color television)
Egalitarian relations among engineers, companies

The Planar Process
Isaac Asimov said this was
"the most important moment since man emerged as a life
form"… perhaps with a bit of exaggeration.
At the end … (1960’s)Situation had changed dramaticallyPeninsula had become major electronics center– A workforce of 58,000– Half to 2/3rds employed in electronics
The main center for development and production of power-grid tubes, microwave tubes, semiconductors, ICs – Half of the microwave tubes – In virtually every advanced weapons, space system – In a wide range of industrial goods (broadcast, uWave
ovens)Central to the US defense effort and to the US manufacturing economy

Silicon Valley Business Climate
East’s large, vertically integrated firms– Protect their current products; adjust
slowly to swift technological and market changes
– Protective, inward, monopolistic (ATT, RCA, IBM); Dependent on Government
SV: highly fragmented, decentralized structure– Specialized firms, flexible, engineering-driven– Dense regional network of small & medium-size
firms that support each other; common work force– Autonomous and often competing teams– Adapt more rapidly to change– Thrived in the new environment
(Ref: Arjun Saxena 1994)
Silicon Valley – ThemesPractices, skills, and competencies– Accumulating here for more than 40 years– Communities of hobbyists - Collaboration– Strong universities (SJSU, UC-B, Stanford …)– Analog and digital techniques (now biotech, sw, cloud)– Access to networks of engineers, financiers and
entrepreneurs– Unique expertise in process, manufacturing,
product engineering, sales, and marketing – Formula to develop and grow electronics companies– Work around/supersede monopolies, patents

"Making Silicon Valley: Roots in Ham Radio"
In Christophe Lécuyer's book "Making Silicon Valley: Innovation and the Growth of High Tech, 1930-1970", it is clear that without ham radio, none of this would have happened -- the Santa Clara Valley would likely have remained an agricultural area. "Silicon Valley" would have been in New York or New Jersey. Paul Wesling will relive some of the developments from the 1930's, when local hams re-invented around the RCA patents on tubes, won Navy contracts during WW II, then developed the vacuum technology that became the cornerstone for vapor-phase epitaxy, the key technology for the transistor and planar IC processes. Isaac Asimov said this was "the most important moment since man emerged as a life form," perhaps with a bit of exaggeration. Paul Wesling (KM6LH) was present at the dedication of an IEEE Engineering Milestone plaque in Palo Alto last spring on the 50th anniversary of the development of the planar process at Fairchild Semiconductor. He is an engineering graduate of Stanford, and is communications director and editor/webmaster for the SF Bay Area Council of the IEEE.
Silicon Valley – Themes
Practices, skills, and competencies – Accumulating here for more than 40 years– Community of electronics hobbyists – Analog and digital techniques – Access to networks of engineers,
entrepreneurs, and financiers – Unique expertise in manufacturing, product
engineering, sales, and marketing – Develop and grow electronics corporations

Before 1920 …
“Valley of the Heart’s Delight”
The Santa Clara Mission
Humble Beginnings
San Francisco Peninsula in the ’20’s – An industrial backwater (NY, NJ, Chicago,
Detroit)
– A few radio enterprises– Workforce of a few hundred machinists,
maybe 80 engineers – Operating in shadow of Radio Corporation
of America (RCA) and large East Coast firms Controlled most of the electronics technology Made most of the components, tubes, etc

William Eitel
Family with strong mechanical orientationFather designed aircraft engines (1910s) Managed a granite quarry, small stone-carving businessE. J. Hall (uncle) established Hall-Scott Motor Car Company in Oakland– One of first automotive companies on the West
Coast– Specialty: small-scale production of sports cars– Designed and built an aircraft engine
"Liberty engine" Used in most American military aircraft during World
War I
Status of Spectrum
Short waves were forsaken portion of spectrum– Under 200 meters (over 1.6 MHz) were “worthless”
– Above the current AM broadcast band – Given by Dept of Commerce to amateurs in 1922
Waves over 200 meters “more potential”– Assigned to the military, RCA, AT&T, broadcasting
networksSo hobbyists took over the short waves– 1923: used 100-meter waves (3 MHz) to Europe– Found short waves far superior over great
distances – A fraction of power used by the long-wave stations

Following our Heroes …
Litton did graduate work in EE at Stanford– Small department (3 instructors)– Electric circuits, AC machinery, pwr transmission– Theory of vacuum tubes– Course (first in 1925) on communication
engineering fundamentals – Thesis: instrument that recorded, helped
visualize short radio waves– Worked at Bell Labs 2 years: short-wave
radio system for transatlantic telephony
The Depression
IT&T, Dollar did poorly– IT&T moved Federal Telegraph to New Jersey
– Dollar layoffs: kept only Eitel, McCulloughLitton stayed in California– 1932, used $6,000 in savings– Established a small proprietorship– Litton Engineering Laboratories– Built vacuum tube shop on parents'
property
“The Origins of Silicon Valley”For Int’l Wafer Level Packaging Conference
November 6, 2013
40
The Depression
Eitel, McCullough built a commercial business– Within smaller Heintz and Kaufman– Commercialized a new transmitting tube– Developed for their own use in amateur radio– More reliable than the one from RCA
Operating poorly at the very high frequencies Work only at low voltages Serious limitations for ham radio use
– Hams applied high voltages for high power output– Doubling the voltage increase power by a factor of
4 Operated efficiently at high (HF) and very high (VHF)
frequencies – sold to ham markets
Patents expiring;Sherman antitrust suit; consent decree
The Klystron
Sperry (NY) invested, got exclusive rights– Bought lathes, welders, pumps from LittonLitton made klystrons for IT&T, for France– Needed for war effort, French radar– Split with Stanford group to avoid patent
issues– Transformed klystron from lab to
production– Too late for France to use (armistice with
Germany in 1940) – Litton became IT&T’s de facto VHF and
microwave design arm– Continuous-wave klystrons, VHF/radar
“The Origins of Silicon Valley”For Int’l Wafer Level Packaging Conference
November 6, 2013
41
Litton During the War
As Litton improved the klystron, Sperry patented inventions and methodsLitton consulted for Federal Telegraph (NJ)New plant design for quality, yield:– Vacuum pumps, maintenance in basement– First-floor plant reconfigurable; cleanliness– Gas-purifying machines, materials purityHelped refine magnetron for late War work
Litton During the War
National Defense Research Committee – Threat from Japan: deployed microwave
radar – Contract to develop jamming capability– Continuous waves at high power– Operate at 10 centimeters (3 GHz)– Novel methods to get “hard” vacuum– Very different from GE, Sylvania
magnetrons– NDRC cancelled GE contract– Navy, Army, Army Air Force wanted
jammers– Very profitable for Litton Engineering Labs

Fast Forward to Silicon Valley
Silicon Valley continues to be the leading high-tech hub: – Large number of cutting-edge
entrepreneurs– Engineers and venture capitalists– Local universities and research– Supporting industriesThis phenomenon can be traced back to ham radio operators– Early developments in radio in S.F.– Breaking of RCA patents to make better
tubes– Collegial spirit from hams, hobbyists
Remembering the Good Ol’ Days
Do some of you remember these pioneers? Did you work with them? Know them as hams?Did any of you work at these companies?What other stories can be told?
