We also made preservation photographic negatives to assure long-term persistence of the images. Earlier this year we acquired an even larger photo collection from the American Vacuum Society , of members at meetings and on other occasions. This collection will be processed in a similar manner. Donations from scientists, their families and colleagues are what make the Emilio Segr Visual Archives uniquely useful. We regularly request portraits from scientists identified as significant by prizes or our surveys, and nearly all respond generously.
Photos also come from historians and others.
A number of interviews were received by the Center. Some are now available for research but most are still being processed. AIP s Post-doctoral Historian, Alexei Kojevnikov, conducted an interview with Philip Anderson . Jean Yehle interviewed William Hay and Cesare Emiliani and Donald Moore . Spencer Weart interviewed Jack Eddy .
