Then there was the low-paid functionary who took care of horses for people who needed their services. There was a famous doctor so named. Can you remember it?

All I can think of is:

stable boy ... Nope, no Dr. Stable Boy
groom ... Nope, no Dr. Groom that I know of
ferrier ... Nope, no Dr. Ferrier that I know of

Hey! Define "low-paid"!
