In 2012 the Center for Land Use Interpretation acquired a set of seven
rolodexes from the dispersed collection of former Los Alamos National
Laboratory employee Ed Grothus, who operated a salvage company of lab
cast-offs, known as The Black Hole.
Now part of the Center's Radioactive Archive, the rolodexes contain
thousands of business cards kept by some unknown office in the lab over
the 1960s and 1970s--the peak of the arms race and its technological
development. They are a physical record of everything from major
military contractors to obscure high- and low-tech software widget
suppliers-many of which are no longer extant, or have evolved.
The selection of 150 cards may be viewed as a snapshot of synergies
between the business community and America's atomic might. On the one
hand, they are a direct indexical connection from the recent past to the
sources of creating the most sophisticated and powerful national defense
technologies in the world. On the other hand, they are obsolete
information, relics of a former usefulness. As a specific printed
historical record--superbly reproduced in full color--they are relevant
to a potential understanding of the present; they are evocative evidence
of the links that formed the secret technology of our nation.
