Here in the Emilio Segrè Visual Archives, we have something we call our “box of mysteries” – a box full of photos that have no identifying information. In May this year, we shared some of these mystery photos with our newsletter, blog, and social media followers to see if we could get help with identifying them. Readers gave a fantastic response by email and phone and we were thrilled to be able to identify five out of seven of the mystery photos. We’ve cataloged these newly-identified images and they are available to view on our website.
December’s Photos of the Month showcases May’s mystery photos with NBLA follower-provided identifications. There will be a new set of mystery photos coming shortly in the History Center Newsletter and online, so be sure to subscribe to the newsletter and check the Niels Bohr Library & Archives blog later in December.
