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 the migration is complete so that you may obtain our copies for free. If you cannot wait, 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.

For more information, please visit our FAQ page on the Ex Libris Universum blog.

Howard and Clayton in Howard's Livermore home.  Mike Howard did his PhD thesis with Clayton at Rice University during 1970-73.  Howard has been an undergraduate at Baylor University in Waco, TX.  He accompanied Clayton several times to Cambridge for research at Hoyle's institute and became a fixture of the 'Rice mafia' in Cambridge. Howard's work included studies of explosive Helium burning in supernova shells and the origin of rare nuclei from seen nuclei in that process (ApJ 1971).
