Sorry, I should've posted some links. Here is the same exact article posted twice:
Biewer Terrier History Biewer Terrier Registry History for the Biewer Breed
Some further info:
History Biewer Breed Club International ~ Biewer Health Registry ~ The first Health Registry for the breed!!!
These are just a couple of organizations that discuss their origin. And yes, it would be nice to hear from a Biewer breeder.
