What does lucubrator mean?
A lucubrator is a person who studies, writes, or does other intellectual work at night. The word is especially associated with the scholarly ideal of burning the midnight oil: rising after sunset, concentrating through the quiet hours, and often producing translations, annotations, commentary, or other learned work before dawn. Its modern use is literary and relatively rare, so it may sound affectionate, whimsical, or deliberately traditional in contemporary English. A lucubrator is not simply anyone who happens to stay awake late; the term implies sustained and usually serious intellectual activity. The word can therefore be used to evoke the discipline and solitude of a scholar whose best work is done after the rest of the world has retired. It is a vivid choice for describing a nocturnal scholar, especially in historical or literary prose.

A lucubrator was literally a “night worker”: a scholar who turned the hours meant for sleep into hours of study and writing.

Etymology of lucubrator
The word comes from Latin lucubrator, meaning a night worker or one who studies by night. It was formed from lucubrāre, “to work or study by candlelight at night,” and the noun-forming suffix -tor, denoting an agent. The related English word lucubration preserves the same idea of nocturnal study, while lucubrate means to work on something late at night. The Latin terminology belongs to the tradition of late-night scholarly composition described by classical and Renaissance writers.
