Intergraph History


In 1969, having helped Apollo 8 orbit the Moon, the founders of Intergraph left IBM to start a consulting company - M&S Computing. Their first contract was the U.S. Army Missile Command. Soon NASA asked them to design printed circuit boards, and in 1973, they landed their first commercial contract - mapping the city of Nashville.

With a focus on mapping and engineering, M&S became a turnkey graphics company, providing "intelligent" graphics software running on their own enhanced terminals connected to host computers. They developed the first interactive CAD product, IGDS (Interactive Graphics Design Software), which quickly became an industry benchmark.


The earliest M&S Computing terminal was designed to create and display graphic information. Composed of unaltered stock parts from various vendors, the terminals consisted of a single-screen display terminal with an attached keyboard and a “menu" tablet that provided a selection of drawing commands.



Storage tubes were the state-of-the-art in display screen technology, and Intergraph engineers chose the biggest, brightest tube available. These terminals were connected to one central computer, so when one terminal was updating, all the others had to wait.



Intergraph developed a specialized circuit board interface that tripled the speed of screen updates by allowing the display terminal to communicate with the host computer.

The first commercial sale of an M&S system was to the metropolitan government of Nashville/Davidson County, Tennessee USA. The system ran the first version of Intergraph’s original core graphics software, IGDS, and was used for mapping applications.


“Over time, Intergraph’s strengths have been two things: technical excellence and commitment to customers. The city of Nashville contract is a good early example. We priced our digitizing work on Nashville's maps at about $32,000. It ended up costing us $200,000. That was an enormous loss at a time we could ill afford it. But I believe it established us as a company that fulfills its obligations – no matter what.” – Jim Meadlock, CEO, 1969-2000



Intergraph offers its first solution for plant design with a piping application.

Intergraph made users more comfortable by placing the two screens side-by-side with an adjustable screen and digitizing table height.

The Digital Equipment Corporation LSI-11/2 microprocessor enabled Intergraph to create the first primitive Local Area Network (LAN) in CAD history.
