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.

We charge a usage fee per photo if the photo is published, reproduced in a product or publicly exhibited. This is not a license in the legal sense. As a non-profit institution, we do not make any money providing these photographs. It is only by assessing usage fees that we are able to cover the cost of providing publication quality copies of our photos, preserving the photograph collection according to archival standards, and providing access to the collection by maintaining an online image database. The copyright holder may charge a fee in addition to our service fee.

Images are for use in educational projects only and must be used in a respectful manner.

Description: 

The concentration of scientists and engineers at the Boulder Laboratories, National Bureau of Standards, attracts the attention of many foreign colleagues. Dr. W. M. Otto (right), a microwave physicist from Australia where he is in charge of the Microwave Techniques Division, Australian Government Research Laboratories, Melbourne, stopped off recently to visit the laboratories of the NBS Radio Standards Division. During his discussions on ferrites and semi-conductors in John Dalke's (center) section, Otto, on a globe-circling tour to review the impact of solid state sciences on the microwave art, conferred with Leon Steinert (left). Here they examine the latter's investigation of the tensor properties of various semiconductive materials.
