In fact, scores of them are physicians, even surgeons
It seems that more and more J.W. were seeking worldly careers and caught hold of their dream job - being physician. After that they played a role in promotion of what now is the bloodmanagement project. If you start scraching on the surface you will certainly find more. Note: that is in strict opposition to GB Lösch order not to seek wordly careers, a resounding slap for him, that the most clever J.W.s become physicians and achieve to be payed by pharmaceutical companies but all clear their job decision is as well a matter of conscience.
