A NEW ONLINE EXHIBIT DEVOTED TO WERNER HEISENBERG traces the birth of quantum mechanics, the wartime effort to build a German atom bomb, and other episodes from a remarkable life. Prepared by leading Heisenberg biographer David Cassidy, the exhibit is available now on the website www.aip.org/history/heisenberg of the Center for History of Physics, the premier clearinghouse of physics-related archived papers, photos, and taped interviews (3000 hours' worth). Located at the American Institute of Physics in College Park, Maryland, the Center houses the Niels Bohr Library (nbl@aip.org, 301-209- 3184), strong in books from the mid-19th century to the present, and the Emilio Segre Visual Archives (containing 25,000 items). The Center itself possesses several valuable collections of papers and provides support to other institutions in their efforts to archive the papers of important physicists (contact Spencer Weart or Joe Anderson at chp@aip.org). The Center has a prominent place on the Internet (www.aip.org/history), where it maintains the International Catalog of Sources for History of Physics and Allied Sciences. In addition to the Heisenberg site, the Center website is also home to two other widely popular exhibits, one devoted to Albert Einstein and one to JJ Thomson's discovery of the electron. Soon an exhibit devoted to Andrei Sakharov will also be available.
