No not the African Witch Doctor stereotype you see in the movies.
He was of Native American decent and his name was Dr Twigg He had a Pavilion up behind his home where he had several ceremonial pits and practiced his Herbal Medicine
Which is where he got the Witch Doctor reputation from.

Not much is known about him as he kept to himself or who the lady's in the picture are.
But if you had an ailment in days days before close by medical care was available or even affordable people often sought out these Herbal Practitioners Known as Granny Witches , Witch Doctors , Herbalists etc. which today they are known known as a Naturapathic Doctor.

These Old Country Doctors. where highly revered back in the day , when modern medicine did not have answers and there are many still practicing today in Western Pa. including
Dr. Martin Gallagher being one of them who is heard on local radio station WEDO 810 AM
and Dr. Lilian Ronzio of The Natural Way who can be heard on WMBS 590 AM
While there are those who scoff at all natural and Herbal Practices they can be very complimentary to modern medicine.
