Bravo to our blog readers.  All of the mystery images that have been posted thus far have been identified!  So let's move on to the next image. This must be a very serious scholar (You've seen pictures of Da Vinci haven't you??).  Can you put a name with this face?

I have two different views of this prof for you to consider and therefore two photos that need to be filed in the right place. The computer in the first view may help place him in time. I was curious about the sign below the prof in the computer picture so I enlarged it and it reads: IF YOU ARE UNABLE TO CLEAN UP AFTER YOURSELF YOU OBVIOUSLY ARE INCAPABLE OF USING THIS COMPUTER SO GET OFF IT! (OR LEARN TO LEAVE A CLEAN WORKSPACE BEHIND)

I kind of have a feeling that I should know who this guy is -- but I don't. Architecture -- got that. Professor -- check. If it's obvious to everyone but me, then so be it. Let the comments roll! How about that pointer -- doesn't it seem a little out of proportion? Maybe everything looks bigger next to a small scale model!

This is a two-for-one special — ID this person and two unidentified photos find a home! The first photo brings back bad memories of organic chemistry. The 3D molecules that he's holding didn't help me at all. There are some more clues in the second photo. We see a chemistry lab nicely staged with students doing experiments, including a woman with hair and socks that look like trends of the late '80s — which coincidentally was the era when I dropped organic chemistry. :) Who is this prof who kindly shows us what he looks like with and without glasses?

This photograph has been kicking around my desk for some time. The house looked familiar, but I couldn't quite place it. I showed it to my colleagues and they also remembered seeing it before — but where?

Who is this corn cob pipe-smoking, bow tie-wearing professor at the typewriter?

Here's a question about RPI's alma mater -- did the lyrics include the first few digits of pi? The answer is no, but there was a cheer that included it along with some other math lingo. Do you know it? E to the X - DY -DX E to the X - DX cosine, secant, tangent, sine, 3 - point - 1 - 4 - 1 - 5 - 9 square root, cube root, log of pi, DISINTEGRATE THEM, RPI!

Do you know this professor? Can you identify any of the formulas on the blackboard?
