The name Doctor, derived from Latin roots meaning 'to teach' or 'to show', is an occupational surname that has been used for generations to denote individuals who practiced medicine. The use of the term 'Doctor' as a given name is less common but not unheard of. It implies a certain level of respect and perhaps even reverence towards the profession of medicine. As a given name, Doctor could be seen as a way to honor or pay tribute to the medical field, or it might simply reflect a unique naming choice by parents who wish to give their child an unusual and memorable moniker.
"Over the course of a century, the name Doctor was given to just over three hundred children, with peaks in popularity around 1914-1920 and notable drops after 1938."
