About this work
Hans Christian Oersted (1777-1851) was a Danish scientist best known for having discovered that electric currents create magnetic fields. He also designed an instrument for measuring the compressibility of liquids. That instrument was sometimes termed an Oersted apparatus. The term “piezometer” may have been coined by the American inventor and mechanical engineer, Jacob Perkins (1766-1849). There is no inscription on this example; and the registering apparatus has been lost.
