With An Usefull Detection of the Mountebanks of Both Sexes," written by Richard Whitlock, a medical doctor. Probably used even then with a taint of impractical idealism.

There is nothing the matter with the United States except ... the parlor socialists, up-lifters, and do-goods.

Meaning "holder of highest degree in university" is first found late 14c.; as is that of "medical professional" (replacing native leech (n.2)), though this was not common till late 16c.

Similar usage of the equivalent of doctor is colloquial in most European languages: Italian dottore, French docteur, German doktor, Lithuanian daktaras, though these are typically not the main word in those languages for a medical healer. For similar evolution, see Sanskrit vaidya- "medical doctor," literally "one versed in science."
