leanings and some communal property. John Varian became a leader of the Temple of the People at Halcyon, worked as a chiropractor and masseur, wrote theosophist poetry and socialist tracts, and pursued an interest in Irish myth and history. Agnes was the first Halcyon storekeeper and postmistress. John and Agnes had three sons, Russell, Sigurd and Eric. The family was not wealthy, but noted in the community for being loving, humorous and adventurous. All three boys exhibited an early fascination with electricity, which included pranks such as attaching electrical outlets to bed springs and door knobs to give visitors minor electric shocks. Russell was named in honor of the poet "Æ", George Russell, whom John had befriended in Ireland. Russell was dyslexic, and in his childhood he was considered by many to be "slow", although later events would demonstrate the true extent of his intellect; Sigurd was the more outgoing of the older two siblings. Composer Henry Cowell befriended Russell in 1911, when both were in their teens. A piano sonata that Cowell composed for Russell brought Cowell to the attention of John Varian, who, in 1917, asked Cowell to write the prelude for a stage production of John's Irish mythical poetry cycle, ''The Building of Banba''. This piece, titled ''
The Tides of Manaunaun ''The Tides of Manaunaun'' is a short piano piece in B minor by American composer Henry Cowell (1897–1965). It premiered publicly in 1917 in music, 1917, serving as a prelude to a theatrical production, ''The Building of Banba''. ''The Tides of ...
'', became Cowell's most famous and widely performed work. 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 knew the family for more than 30 years, and was a hiking companion of Russell's; the pair made many trips into the Sierras. Adams later used a line from one of John Varian's poems, "...What Majestic Word", as the title of his 1963 ''Portfolio Four'', which he dedicated to Russell's memory. The portfolio, of which only 200 copies were printed, was narrated with the words of John and Russell Varian, and sold as a fundraiser for the Sierra Club.


Careers

Russell earned bachelor's and master's degrees in physics from Stanford University, compensating for his learning disabilities with what was described as hard work and "sheer force of will". Because of his reading and math difficulties, he took six years to graduate, switching from social sciences to physics. His application to the PhD program at Stanford was rejected. He completed his master's degree in 1927, and went to work at

Sigurd was one of the pilots Pan Am selected for their first flights to Mexico and Central America, and while working as an airline captain, he lived in Mexico from 1929 to 1934. From this experience, he discovered many problems with existing maps, finding, for example, that some Mexican charts showed swamps where there were actually mountains. He also realized how difficult it was to land safely or to detect other planes at night or when it was overcast. As a result, he was very familiar with the inadequacies of existing navigational equipment and became interested in ways to make flying safer. In the early 1930s, in addition to a strong interest in

Working together

Sigurd was interested in all-weather navigation systems, and suggested to Russell that together they could create a radio-based technology using

that could detect airplanes at night or in clouds. Russell agreed, and they both quit their jobs, set up their own lab at Halcyon, and began developing plans for a device that could precisely determine the location and direction of an airplane. They initially attempted to create a radio compass, but could not develop a successful design, partly as a consequence of their isolation. They ultimately sought assistance from Russell's college roommate, William Webster Hansen, who was by then a professor at Stanford. With Hansen's help, they came to the attention of the head of the Stanford physics department, David Webster, who hired them in 1936 to work at the university in exchange for lab space, $100 a year for supplies, and an agreement that Stanford University would have half of the royalties for any patents they obtained. After several rejected models, Russell devised a way to use velocity modulation to allow electrons to flow in bunches and to control their speed. The concept of velocity modulation he used had already been described by A. Arsenjewa Heil and Oskar Heil in 1935, though the Varians were unlikely to have known of the work. The brothers and Hansen ultimately created the

The Varians moved to the East Coast in 1940 to work for Sperry, where wartime development of the microwave tube continued. Though little is known of their work in this period (because they were presumably working on classified projects), it appears that they directed Sperry's

and radar work during World War II. The US and Britain were able to use this technology to create radar equipment light and compact enough to fit into aircraft, which was credited with helping the Allies win the war.


Post-war

The Varian brothers and their associates individually left Sperry and returned to the West Coast between 1945 and 1948. After the war, the klystron became an important component in the further development of radar and the microwave industry. It was used in broadcast television and in the development of various

Varian Associates

Russell and Sigurd founded Varian Associates in 1948, along with Hansen and Ginzton. They initially created the company to commercialize the klystron and develop other technologies, such as small linear accelerators to generate

. They also were interested in nuclear magnetic resonance technology. Russell's wife, Dorothy, was also active in the development of the company and its operations. The Articles of Incorporation were filed on April 20, 1948, and signed by nine directors: Ginzton, who had worked with the Varian brothers since his days as a doctoral student; Hansen, Richard M. Leonard, an attorney; Leonard I. Schiff, then head of the physics department at Stanford; H. Myrl Stearns, Russell, Dorothy, Sigurd and Paul B. Hunter. The company began with six full-time employees: the Varian brothers, Dorothy, Myrl Stearns, Fred Salisbury, and Don Snow. Technical and business assistance came from several members of the faculty at Stanford University, including Ginzton, Marvin Chodorow, Hansen, and Leonard Schiff. 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

, of Hewlett-Packard. Russell served as the company president and a board member until his death; Sigurd served as vice president for engineering, and served on the board of directors until his death, sometimes serving as chairman of the board. After the deaths of both Varian brothers, Ginzton became the company's CEO. The company was initially headquartered in San Carlos, California, and started with only $22,000 in funding. Russell's insistence that the company be owned by its employees and his refusal to accept outside investors led to problems in raising additional capital. Hansen mortgaged his home for $17,000 to raise additional cash, and the group sought out funds from their friends. Ultimately, however, the company raised $120,000 of necessary capital via an offer of stock to all employees, directors, consultants, and a few sympathetic local investors who shared the company's goals. Military contracts for technology deemed necessary during the Cold War, including some classified projects, also helped the firm succeed. In 1953, Varian Associates moved its headquarters to

in May, 2010. One of Varian Associates' major contracts in the 1950s was to create a fuse for the atomic bomb. The Varian brothers had initially been supportive of military applications for the klystron and other technologies, on the grounds that they were primarily defensive weapons, but this contract was different. Although politically progressive to the point of having socialist leanings, the Varians considered themselves patriotic at heart and had no sympathy for Soviet Marxism. They also needed military contracts to survive, and relished the technical challenges of this type of work. Nonetheless, as early as 1958, Russell and Sigurd expressed regret for their involvement in developing weapons of mass destruction. Most of the founders of Varian Associates, including Russell and Sigurd, had progressive political leanings, and the company "pioneered profit-sharing, stock-ownership, insurance, and retirement plans for employees long before these benefits became mandatory." Nearly 50 years later, in 1997, the company was still recognized by '' Industry Week'' as one of the best-managed companies in America. In 1998, the Congressional Record noted the 50th anniversary of the founding of Varian Associates, which then employed 7,000 people at 100 plants in nine countries. It had branched out into health care systems, analytical equipment, and semiconductor manufacturing equipment. The company had been awarded more than 10,000 patents. California's 14th congressional district Representative Anna Eshoo called the company a "jewel in the crown of ... Silicon Valley."


Families and personal lives

Russell and Sigurd's brother, Eric Varian, remained in the Halcyon area. He had a career in the central California coast as an electrical contractor, and, beginning in the early 1960s, also assisted the work of his daughter, Sheila Varian, in building a horse ranch, and she became a notable

of Arabian horses. Russell's wife Dorothy provided short-term loans that helped support the Varian Arabian horse breeding program in its early years.


Russell

Russell married twice. From his first marriage, he had a son, George Russell Varian, born on April 22, 1943. Russell's second marriage, in 1947, was to Dorothy Hill. Dorothy, born in 1907, attended

Deaths and legacy

Both Russell and Sigurd died unexpectedly. Russell died of a heart condition in 1959 on a hiking trip in Alaska. He had been scouting locations that were being considered for national parks. Dorothy continued the couple's conservation work, invigorating the Sempervirens Club as a trust fund to acquire lands for conservation. Her efforts helped establish Castle Rock State Park in 1968. She wrote a biography of Russell and Sigurd, titled ''The Inventor and the Pilot: Russell and Sigurd Varian,'' published in 1983. Dorothy died on July 9, 1992. On October 18, 1961, Sigurd crashed his private plane into the Pacific Ocean while flying from Guadalajara to Puerto Vallarta, after losing his way in darkness. The plane crashed about a mile offshore and his passenger, George Applegate, managed to swim ashore and survived. Sigurd was buried in Guadalajara. He had lived the last three years of his life at Puerto Vallarta. He left an estate worth over $3 million, with one-fourth going to "The Sigurd F. Varian and Winifred H. Varian Charitable Foundation," a chief beneficiary of which was a hospital in Puerto Vallarta. Winifred died suddenly on July 11, 1962. The couple's daughter Lorna had commented that her mother had been very depressed after Sigurd's death. The Varian family's interest in the conservation of California's natural heritage has been carried on by Sigurd's son, Jack, owner of the V6 Ranch near
