Varian Associates.

Varian Associates was formed in San Carlos, Calif. in 1948 by Edward L. Ginzton, William W. Hansen, Richard M. Leonard, Leonard I. Shiff, H. Myrl Stearns, Dorothy Varian, Russell H. Varian, Sigurd F. Varian, and Paul B. Hunter with $22,000 of capital and six full-time employees. Its first major product was the klystron microwave tube, developed through research at Stanford University in 1937. The company went on to produce important new products in the fields of radio, radar, television, and electro-photography and eventually became the leading designer and manufacturer of linear accelerators. In 1965 the company merged with Eitel-McCullough. Varian Associates formally divided into three companies in 1999 turning each of its divisions into a separate public enterprise. The three resulting corporations were Varian Medical Systems, Varian, Inc., and Varian Semiconductor Equipment Associates, Inc.
