André-Marie Ampère André-Marie Ampère ( ; ] ; 20 January 177510 June 1836) was a French physicist and mathematician who was one of the founders of the science of classical electromagnetism, which he referred to as "electrodynamics". He is also the inventor of numerous applications, such as the solenoid (a term coined by him) and the electrical telegraph. An autodidact, Ampère was a member of the "Académie des sciences" and professor at the "École polytechnique" and the "Collège de France".
Oliver Lodge Sir Oliver Joseph Lodge, {'1': ", '2': ", '3': ", '4': "} (12 June 1851 – 22 August 1940) was a British physicist and writer involved in the development of, and holder of key patents for, radio. He identified electromagnetic radiation independent of Hertz' proof and at his 1894 Royal Institution lectures (""The Work of Hertz and Some of His Successors""), Lodge demonstrated an early radio wave detector he named the "coherer". In 1898 he was awarded the "syntonic" (or tuning) patent by the United States Patent Office. Lodge was Principal of the University of Birmingham from 1900 to 1920.
