Russell Harrison Varian (April 24, 1898 – July 28, 1959) and Sigurd Fergus Varian (May 4, 1901 – October 18, 1961) were American brothers who founded one of the earliest high-tech companies in Silicon Valley. Born to theosophist parents who helped lead the utopian community of Halcyon, California, they grew up in a home with multiple creative influences. 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.
