Re:
In late 2012, I had the honor of attending a daylong symposium in memory of one of my teachers and mentors, Prof. Saul Roseman. Besides his own contributions to his (and my) discipline, his laboratory turned out a who's who of scientists for three or more decades, including the co-founder of New England BioLabs (the late Don Comb).
One of Roseman's
proteges was the late Prof. Bill Jourdian. Bill gave a short talk at the gathering in the rather large lecture hall in the Biology Dept at my
alma mater. Lacking a laser pointer or other suitable means of gesticulating at the rather large projection screen, he improvised.
(in case it's not obvious from my photo, he's using his rather large walking stick)
I owe my well-honed skepticism mostly to Prof. Roseman, who was hell-bent on making sure that
every graduate student that passed through the department on his watch would understand quite well that
we may be smart... but we're not ever as smart as we think we are.
It takes a certain amount of humility, and an extremely open mind, to study Nature... and especially the biology of carbohydrates.
