A Brief History of the Micrometer Part II: The Bronze Age
This article is based on an original publication by Mitutoyo.
Originating in mid 19th-century France, today's typical micrometer features a standard U-shaped frame with single-handed operation. The birth of the modern micrometer is attributed to French inventor J. Palmer, who received his patent in 1848 for the Palmer System.
The Birth of the Modern Micrometer
Palmer based this compact, handheld micrometer on the same principles as Gascoigne's 1638 invention (A Brief History of the Micrometer Part I: The Early Period). However, with a far more advanced design, Palmer's model would become the foundation on which all modern micrometers would be built - making a considerable impact on the tool's history.
