Even when I was in medical school over fifty years ago, medical eponyms were frowned on
because there were so many, and the names gave no clue. So medical educators demanded
that diseases be named by anatomical, pathological, or physiological attributes.
As a single example, "Lou Gehrig's disease" would mean nothing to doctors in UK.
Now it is called Amyotrophic Lateral Sclerosis.
Here is a URL to a dictionary of eponyms, of both diseases and devices that will
have over 15,000 entries when finished. Imagine trying to remember that many!
