  • Chapter 14 Intergraph
    Chapter 14 Intergraph Introduction Of the “big five” CAD vendors in 1980, Applicon, Auto-trol Technology, Calma, Computervision and M&S Computing, only the last of these, now known as Intergraph, is still a viable thriving business although it has also had its share of highs and lows. The history of Intergraph from the mid-1980s on cannot be completely separated from the history of Bentley Systems, the company that developed and currently markets MicroStation. This chapter will describe the MicroStation story from Intergraph’s point of view, leaving it to a separate chapter on Bentley (Chapter 10) to describe in depth the breakup of this corporate partnership and how Bentley eventually went its own way. Establishment of M&S Computing Intergraph was started as M&S Computing in February 1969 by a group of engineers who were working for IBM’s Federal Systems Division in Huntsville, Alabama developing guidance software for the Saturn rocket. The group consisted of Jim Meadlock, his wife Nancy, Terry Schansman (the S of M&S), Keith Schonrock, and Robert Thurber. James Taylor joined three months later as employee #6. This was an extremely loyal group of founders with all of them except for Schansman sticking with the firm through the 1980s and much of the 1990s. In fact Taylor was the company’s president and CEO when he retired for the second time in July 2003. Schansman left the company when it went from being a software contractor to marketing turnkey graphics systems. He wanted to stay in the software business. Unfortunately, he died from a heart attack a few years later.
