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?
