Intergraph

Intergraph Corporation was an American software development and services company, which now forms part of Hexagon AB. It provides enterprise engineering and geospatially powered software to businesses, governments, and organizations around the world, and operates through three divisions: Hexagon Asset Lifecycle Intelligence (ALI, formerly PPM), Hexagon Safety & Infrastructure, and Hexagon Geospatial. The company's headquarters is in Huntsville, Alabama, United States. In 2008, Intergraph was one of the one hundred largest software companies in the world. In July 2010, Intergraph was acquired by Hexagon AB. Intergraph was founded in 1969 as M&S Computing, Inc., by former IBM engineers Jim Meadlock, his wife Nancy, Terry Schansman (the S of M&S), Keith Schonrock, and Robert Thurber who had been working with NASA and the U.S. Army in developing systems that would apply digital computing to real time missile guidance. The company was later renamed to Intergraph Corporation in 1980. One of Intergraph's major hardware projects was developing a line of workstations using the Clipper architecture created by Fairchild Semiconductor. Intergraph was one of only two companies to use the chips in a major product line. Intergraph developed its own version of UNIX for the architecture, which it called CLIX.
