Peter Sachs Collopy is university archivist and head of Archives and Special Collections at the California Institute of Technology. Claudia Bohn-Spector is an independent curator.
""For more than a century, the California Institute of Technology has been a world-leader in science and technology. Less well known is the rich visual culture--whether in the form of fine art, astrophotography, architectural drawings, or biological illustrations--that has accompanied and amplified Caltech's research mission. With Crossing Over, Sachs Collopy and Bohn-Spector have assembled a marvelous collection of essays and artworks which showcase how the visual arts have been essential ingredients in Caltech's accomplishments. This book is a joy to view."" --W. Patrick McCray, University of California, Santa Barbara
