I procrastinated painting this duck. For some reason, I was sure it’d be terrible. It’s OK.
I wondered where the term “quack” in reference to bad doctors came from. Here’s what I found:
The oldest recorded use dates back to 1638 (Francis Quarles’ 1638 book, Hieroglyphikes of the Life of Man) Mental Floss.
It’s from the old Dutch term “quacksalver” which means someone who cures using home remedies. Salver, as you can infer, refers to “salve” with ointments and such. Somewhere along the line, it morphed into the concept of someone who peddles their own medical tools and remedies with little to no qualification.
