The word micrometer is a neoclassical coinage from Greek micros, meaning "small", and metron, meaning "measure".
If we discuss the history of this device, the first ever micrometric screw was invented by William Gascoigne in the 17th century, as an enhancement of the vernier; it was used in a telescope to measure angular distances between stars and the relative sizes of celestial objects.
Henry Maudslay built a bench micrometer in the early 19th century that was jocularly nicknamed "the Lord Chancellor" among his staff because it was the final judge on measurement accuracy and precision in the firm's work.
Micro metre now a days is a common school lab instrument. I am pasting a link for a video that I find interesting and quite simple. Features and working of the instrument have been discussed very clearly in this video.
