Emilio Segrè Visual Archives

More than 30,000 photos of scientists and their work


Attention ESVA patrons:

The Emilio Segrè Visual Archives’ site is moving soon and adopting an open access approach to digital image sharing. Once we have transitioned to the new site in 2021, we will no longer charge for our high-resolution digital images or usage fees (note that we do not hold copyright to all the images in our collections and you will still need to obtain permission for those which we do not own).

If you are working on a long-term project, we advise you to wait until 2021 so that you may obtain our copies for free. If you cannot wait until 2021, email us at nbl [at] aip.org and we will do what we can to assist you. We will not be offering refunds for past purchases.
