Biography  Joseph John Thomson was born in Manchester, on April 18  Married Rose Elisabeth in 1890, and had two children  He was awarded the 1906 Nobel Peace Prize in Physics  He passed away on August 30, 1940

Famous Discoveries  Measured how a magnetic field and an electric field deflected a cathode ray tube, and concluded that cathode rays are made of negatively charged particles and that they come from the cathode, the negative end of the cathode ray.  Thomson named these negatively charged particles electrons  Discovered that an electron’s electrical charge is 1.76x10^8 coulombs per gram
