Doctor
A surname that usually began as a nickname or occupational label for a learned or medical man.
The #9,384 most common surname in the United States (2010 Census) — about 1 in every 89,104 Americans shares it.
Etymology
Doctor comes from the Latin word doctor, meaning “teacher” or “one who teaches,” from docere, “to teach.” In English, it came to mean a learned man and later a physician, so the surname could arise either as a nickname for someone with scholarly standing or as an occupational name for a doctor in the modern sense. Some historical references also show it used more loosely for church or university figures with learned roles.
History
The surname is uncommon, but the word itself was long used in Britain as a title for learned men, especially in law, theology, and medicine. Historical records also show forms like Doctor Dubber or references to “Doctor of Laws,” which suggest that the surname could sometimes be attached to a person’s role or reputation rather than inherited in a fixed family line from the start. In some cases it may have overlapped with bynames for a person known for scholarship or healing.
