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?
