History
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. In 1987, Intergraph bought the Fairchild division responsible for the chip.
In 1997, Intergraph began pursuing patent infringement litigation against Intel and other computer hardware manufacturers based on the intellectual property developed in Clipper. Intergraph negotiated major settlements with Intel, HP, Texas Instruments and Gateway, earning the company over $394M. In 2000, Intergraph exited the hardware business and became purely a software company.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Intergraph”, the useful work is to connect “american software development and services company” to the records capable of establishing context and consequence.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Sep 2, 2026. The linked authority identifier is Q1424984. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2008, 2010, 1969 and 1980.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
