Klystron

reflex klystronKlystron tubeklystrons
The brothers showed an early interest in electricity, and after independently establishing careers in electronics and aviation they came together to invent the klystron, which became a critical component of radar, telecommunications and other microwave technologies.
A klystron is a specialized linear-beam vacuum tube, invented in 1937 by American electrical engineers Russell and Sigurd Varian, which is used as an amplifier for high radio frequencies, from UHF up into the microwave range.

Varian Associates

In 1948 they founded Varian Associates to market the klystron and other inventions; the company became the first to move into Stanford Industrial Park, the birthplace of Silicon Valley.
It was founded in 1948 by Russell H. and Sigurd F. Varian, William Webster Hansen, and Edward Ginzton to sell the klystron, the first vacuum tube which could amplify electromagnetic waves at microwave frequencies, and other electromagnetic equipment.

John Osborne Varian

The Varian brothers' parents, John and Agnes Varian, were born and raised in Ireland, and were members of the Theosophical Society in Dublin.
Two of his sons, Russell and Sigurd Varian, became notable inventors and went on to found Varian Associates, one of the first companies in Silicon Valley.

In 1950, the Varians were awarded the John Price Wetherill Medal for the development of the klystron, and both were posthumously inducted into the Silicon Valley Engineering Council Hall of Fame in 1993.

Both brothers were noted for their progressive political views; Russell was a lifelong supporter of the Sierra Club, Sigurd helped found the housing cooperative of Ladera, California, and Varian Associates instituted innovative employee policies that were ahead of their time.
Early members of the cooperative included author Wallace Stegner and Klystron tube inventor Sigurd Varian of Varian Associates.

Born to theosophist parents who helped lead the utopian community of Halcyon, California, they grew up in a home with multiple creative influences.
Varian's sons Russell (1898–1959) and Sigurd (1901–1961), who spent part of their childhood in Halcyon, invented the klystron, an important microwave amplifier tube, and founded the Varian electronics empire.

Sperry Corporation

SperrySperry RandSperry Gyroscope Company
The klystron, a microwave tube, was noticed in 1938 by Sperry Gyroscope, who gave the Varian brothers and Hansen a contract to do further work.
Sperry supported the work of a group of Stanford University inventors, led by Russell and Sigurd Varian, who had invented the klystron, and incorporated this technology and related inventions into their products.

Nuclear magnetic resonance

Russell gained patents for technology related to nuclear magnetic resonance (NMR), as used in magnetic resonance imaging (MRI), thermionic tubes, and various radar technologies.
Russell H. Varian filed the "Method and means for correlating nuclear properties of atoms and magnetic fields", on July 24, 1951.

Edward Ginzton

Edward Ginzton, who later helped the brothers establish Varian Associates, stated: "[Sigurd] felt that Hitler could easily establish bases in Central America, from which his planes could fly into the United States at night, or at low elevations, and drop bombs, without ever being detected."
As a student at Stanford University, Ginzton worked with William Hansen and brothers Russell and Sigurd Varian.

Ansel Adams

Cowell was also a music tutor of Ansel Adams, and the Varian family in turn became friends with Adams, who became friends with Russell and Sigurd through their mutual activity in the Sierra Club.
Adams published his fourth portfolio, What Majestic Word, in 1963, and dedicated it to the memory of his Sierra Club friend Russell Varian, who was a co-inventor of the klystron and who had died in 1959.

They ultimately sought assistance from Russell's college roommate, William Webster Hansen, who was by then a professor at Stanford.
In 1937, brothers Russel H. Varian and Sigurd F. Varian came to Stanford to work on the foundations of what was to become radar.

In 1953, Varian Associates moved its headquarters to Palo Alto, California, at Stanford Industrial Park – noted as the "spawning ground of Silicon Valley" – and was the first firm to occupy a site there.
1044 Bryant was the home of Russell Varian, co-inventor of the Klystron tube.

Francis Farquhar, an accountant and friend of Russell's from the Sierra Club, later became a director, as did Frederick Terman, Dean of Engineering at Stanford, and David Packard, of Hewlett-Packard.
Terman's students at Stanford included Oswald Garrison Villard, Jr., Russell and Sigurd Varian, William Hewlett, and David Packard.

The first powerful sources of microwaves were invented at the beginning of World War 2: the klystron tube by Russell and Sigurd Varian at Stanford University in 1937, and the cavity magnetron tube by John Randall and Harry Boot at Birmingham University, UK in 1940.
