The original interview elements, 16mm negative and 1/4" audio reel to reel, were preserved during 2010-2016 due to the generosity of a grant from the Andrew W. Mellon Foundation. Thanks to a grant from the National Historical Publications and Records Commission (NHPRC), the preserved films were digitized to create 10-bit uncompressed HD files and the original 1/4" elements were digitized to create 24-bit 96kHz .wav files. The picture and audio were then reassembled at the Film & Media Archive.
