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.

Caption by AP dated January 18, 1939:

"A gigantic new atom smasher, which scientists at Massachusetts Institute of Technology hope will some day be capable of improving x-ray treatment of human diseases, was dedicated by the institute's president, Dr. Karl T. Compton at Cambridge, MA.. President Compton holds a 'time capsule' packed with scientific literature which he sealed in a great slab of iron which will form the base of the big machine. Looking on is Dr. Robley D. Evans, in charge of cyclotron research."
