Who are those guys at the top of the page?

From left to right:

Added 6/2/10: I recently “discovered” a very short article in C&ENews (S. Wilkinson, “Symmetry Rules!” January 27, 2003, 81(4), 59) celebrating the publication of the original Woodward-Hoffmann article in 1965. The article is nice to look at because it contains a link to the first W-H article and also photos of both men that were taken around the time when the Rules were published. Hard to believe that they were both younger than I am now (and Hoffmann was much closer to your age than to mine).
