Technology: Just Dig While You Work

Where does the world's foremost designer of high-speed computers get his inspiration? Apparently deep in a dirt tunnel beneath his Wisconsin home, according to John Rollwagen, the chairman of Cray Research. As Rollwagen tells it, Seymour Cray, the company's elusive founder, has been dividing his time between building the next generation of supercomputers and digging an underground tunnel that starts below his Chippewa Falls house and heads toward the nearby woods. "He's been working at it for some time now," says Rollwagen, who reports that the tunnel is 8 ft. high, 4 ft. wide and lined with 4-by-4 cedar boards. When a tree fell through the top of the tunnel several years ago, Cray used the opening to install a periscope-equipped lookout.

For Cray, the excavation project is more than a simple diversion. "I work when I'm at home," he recently told a visiting scientist. "I work for three hours, and then I get stumped, and I'm not making progress. So I quit, and I go and work in the tunnel. It takes me an hour or so to dig four inches and put in the 4-by-4s. Now, as you can see, I'm up in the Wisconsin woods, and there are elves in the woods. So when they see me leave, they come into my office and solve all the problems I'm having. Then I go back up and work some more."

Rollwagen knows that Cray is only half kidding and that some of the designer's greatest inspirations come when he is digging. Says the chairman: "The real work happens when Seymour is in the tunnel."
