This image is in the files of the Laboratory of Molecular Biology in Cambridge England, and they hold the copyright. I place here excerpts of two e-mails from that organization releasing this image without conditions for Wikipedia use.

"I have, through various discussions with people here, been able to get approval for you to use the image of John Kendrew on your Wikipedia entry. As you know this is not the sort of approval we normally give, but it was felt that we could in this case. However, we are only prepared to let you have a low resolution image, which is of good enough quality for web pages and people's own use, but if people require a higher resolution copy for publishing or commercial use, they could then get in touch with us. If this is OK then please use the image and credit it to MRC Laboratory of Molecular Biology." "I thought we had already agreed this, what other data do you need? As I mentioned in my email, the photo should be credited to "MRC Laboratory of Molecular Biology", as we are the copyright holders. Requests for higher resolution images should be sent to archive@mrc-lmb.cam.ac.uk"
