J.J. Thompson was a physicist who helped revolutionise the knowledge of atomic structure by his discovery of the electron in 1897. He received the Nobel Prize for Physics in 1906. He entered Trinity College, Cambridge in 1876, and remained a member of the College for the rest of his life, as a Lecturer, Master and then Professor of Physics. Thomson's early interest in atomic structure was reflected in his Treatise on the Motion of Vortex Rings. His outstanding work was an original study of cathode rays culminating in the discovery of the electron, which he announced in a lecture to the Royal Institution in 1897. He published numerous books and treatises and won many awards and medals for his work.
