3 Precision Measurement Technical Specifications The first micrometer was patented by the French inventor Jean Laurent Palmer in 1848 as calibre à vis et à vernier circulaire (screw caliper with a circular vernier).the introduction of the micrometer to the industrial world came about by the visit of two American engineers, Joseph R. Brown and Lucian Sharpe to the Paris Exhibition in At that time, their attention was drawn to Palmer s invention, which greatly interested them. After making some improvements to the design, Brown & Sharpe received a U.S. Patent in 1899 for a mechanical direct reading mi crometer. The product was manufactured on a large scale and marketed successfully by the two partners. Today, Brown & Sharpe continues to make external microm - eters with the same features. Shown here are some early examples of Brown & Sharpe s precision hand tools; many such examples can still be found in good working order some 100 years later. Today, new and innovative products like the MICROMASTER line of digital micrometers con tinue this amazing tradition.
