. . . Origin of the name LMRK

Bob Limbaugh and Roice Nelson made the first sales call for what became Landmark Graphics Corporation following the 1982 EAEG (European Association of Exploration Geophysicists) Convention held in Cannes, France. They met at the underground station by Big Ben (Parliament) in London and walked down the street to ICI Petroleum and Mr. John Dolhman. After a two hour meeting describing the proposed new company John asked what the name of the company was so that he could tell his partners in the Ninian Field at Cheveron. Bob thought for a minute, and said Diamond Graphics Corporation.

Kevin Kinsella, the unknown founder, had registered the company as GeoGraphix Corporation in Texas and California. However, Bob did not want the prefix 'geo' tied to the name for fear it would be lost in the crowd. He explained his logic by saying "My middle name is stone, the most valuable stone is a diamond, and therefore we will call the company Diamond Graphics Corporation."

After returning to Houston, the four active founding partners met together, for the first time, and the name of the company came up. Andy Hildebrand and John Mouton were adamant that Diamond Graphics Corporation was not a good name. John stessed he wanted the name to include 'Corporation' rather than 'Incorporated' because the world sees a 'Corporation' as being more substantial. We agreed the company would not be called either GeoGraphix Corporation or Diamond Graphics Corporation.

A few days later Bob came into the new office and said what about Landmark Graphics Corporation. Everyone immediately agreed. Then there was an effort to break the name apart and explain it's orgins with words like: "Four oil & gas professionals have jointed together to form a company to interactively 'mark' the 'land'" Even published something like this in the Seismic Acoustics Laboratory / Allied Geophysical Laboratories newsletter. Then there was the discussion, led by Bob, where the word Landmark was broke apart in a different way: LAN, Local Area Network (one of Andy's contributions); DMA, Direct Memory Access (one of John's contributions); and RK, Roice's Knowledge.

Several years later, when Hardie Morgan polled the principals for the stock exchange name. One of his options was LMRK, which became the selected name.
