How it started

History

Varian was founded in 1948 as Varian Associates by Russell H. Varian, Sigurd F. Varian, William Webster Hansen, and Edward Ginzton to sell the Klystron, the first tube which could generate electromagnetic waves at microwave frequencies, and other electromagnetic equipment.

By 1999, Varian Associates had branched into semiconductor, vacuum tube, and medical device fields. On April 2, 1999, these divisions split to become Varian Semiconductor, Varian, Inc., and Varian Medical Systems.

In April 2021, Siemens Healthineers acquired Varian Medical Systems in an all-stock deal valued at $16.4 billion.

Acquired companies

Before its acquisition by Siemens Healthineers, Varian Medical Systems had acquired other companies, including Pan-Pacific Enterprises, ACCEL Instruments, Bio-Imaging Research, Inc. Sigma Micro Informatique Conseil, Argus Software, Dosetek Oy, Velocity Medical Solutions. and MeVis Medical Solutions AG.
