I hope the start of the new academic year has been treating you well. I was reading an article about James Lind, who was the man who is credited with curing scurvy among seafaring men (and women, though probably not many back then!) Surprisingly it seems he wasn't the first to notice the correlation with lack of citrus fruits and scurvy but he was the first learned man to publish it. If you have some time it is well worth a read.
