What? Where? When? Who?

The IUCr website is building a library of photographs of crystallographers from around the world over the past 30 years. If you go to the website and search on a meeting and your name, chances are you will get a dozen hits of photos of you at crystallographic meetings somewhere in the world.

We are asking you to help identify the people in these photos and the crystallographic meetings they were taken at. The first person who can correctly identify the meeting sites and at least five people in each photo will receive a prize of a $50 donation to their preferred crystallographic charity (i.e. Student travel fund for ACA, ECA or AsCA annual meeting).
