I've never met him or seen him in person, but I truly admire Dr. Komaroff. I first became aware of him in 1987, but I think he first started to notice ME/CFS cases as far back as back in the 1970's.
It's true that he was one of the 16 authors of the
paper that proposed to replace the the name of the then current "chronic Epstein-Barr virus syndrome" with the term "chronic fatigue syndrome" (after the Epstein-Barr virus was seen to be no more prevalent in cases than other herpes viruses and measles), but that group did not invent the term. The term "the chronic fatigue syndrome" had been floating around and gaining traction as an alternative for a couple of years before that.
Komaroff has publicly expressed his regret for endorsing the term, which he has called "a terrible name." I'm not aware that any of the other authors of that paper have contributed to the field for some time.
Komaroff may not be flashy (which is one of the things I admire about him), but he is what you would want a physician/researcher to be: methodical, circumspect, highly informed, committed and
involved with getting information to patients. I think he's a hero of the field.
