ESI was founded in 1944 In 1953, BECO's Douglas C. Strain and three other investors bought out Strain's partners at Brown and formed a new company,
Electro-Measurements Inc., which used the
brand name "ESI" in marketing. The acronym stood for "excellent scientific instruments", but the company's name remained Electro Measurements Inc. until 1959, when it was changed to "ESI, Inc." and finally in 1960 to
Electro Scientific Industries, Inc. (ESI). Prior to about 2000, the company was usually referred to as having been founded in 1953. Douglas Strain was the company's
CEO and
board chairman from 1953 until 1980, and remained on the board (continuing as chairman until 1985, then vice chairman) until fully retiring in 1999. In 1970, ESI began developing
laser trimming systems for
resistor circuits, and had to be rebuilt. In 1962, ESI announced plans to create a new development called "Sunset Science Park", to be built in the
Cedar Mill area of unincorporated
Washington County, Oregon, designed to attract other technology companies, with ESI as an anchor. The company moved its headquarters to the Sunset Science Park location in 1963, and the manufacturing facilities followed in 1966, vacating the Macadam Avenue site. The complex on N.W. Science Park Drive, which remained ESI's headquarters until 2021, had a Portland mailing address, but was not in the city of Portland proper; it occupied
unincorporated land which is now adjacent to the city limits of
Beaverton. ESI became a
publicly traded company in 1983. It traded on the
NASDAQ stock exchange under the
ticker symbol ESIO. The company opened its first foreign sales office in 1978, in
Munich,
Germany, and later opened offices in several countries in
Southeast Asia. As of 2007, the company also had offices for direct sales in several European countries, as well. Several small companies were acquired by ESI in the late 1990s, including Dynamotion Corp. (of California) in 1997, Chip Star Inc. (California) in 1997, Applied Intelligent Systems Inc. (AISI) (Michigan) in 1997, and Testec Corp. (Arizona) in 1999. A new manufacturing facility was opened in
Klamath Falls, Oregon, in early 2001. The company acquired California-based New Wave Research Inc. in 2007. At the beginning of 2009, Electro Scientific had around 700 employees, about half of whom were located in Oregon. The company acquired
fiber laser manufacturer Eolite Systems in June 2012, the semiconductor systems business from GSI Group in May 2013, and Chinese laser firm Wuhan Topwin Optoelectronics Technology Co. in January 2015. In August 2016, the company announced that Michael Burger, formerly CEO of
Cascade Microtech, would succeed Edward Grady as CEO effective October 3, 2016.
Annexation fight In 2005, ESI joined
Columbia Sportswear,
Tektronix and other Washington County companies in an effort led by
Nike to convince the
state legislature to prohibit the practice of forcible
annexation of "islands" of unincorporated land that have become surrounded by a city. The Nike effort stemmed from an aggressive annexation policy being practiced by the city of Beaverton in 2004, under which the city had added more than of unincorporated land, including the headquarters of
Leupold & Stevens (located almost adjacent to ESI, but on the opposite side of the
Sunset Highway freeway). Although the then-headquarters sites of ESI and Columbia are not on "islands" surrounded by Beaverton, both directly
abut the city boundary, and company officials were concerned about the likely eventual effect of the city's annexation practices should future annexations cause their properties to become part of such an island. The 2005 Oregon Legislature enacted a law prohibiting Beaverton from any forced island-type annexations for two years and additionally included language effectively banning Beaverton from forcibly annexing any of Electro Scientific Industries' property—whether an island or not—for at least 30 years. ==Sale of company to MKS==
