Gourt Home::Gourt :: Oliver Joseph Lodge
Sir Oliver Joseph Lodge (June 12,1851 - August 22, 1940), born at Penkhull near Stoke-on-Trent and educated at Adams' Grammar School, was a physicist and writer involved the development of the wireless telegraph. Lodge, in his Royal Institution lectures ("The Work of Hertz and Some of His Successors") coined the term "coherer" and gained the "syntonic" (or tuning) patent from the United States Patent Office.
Career
Lodge obtained a Bachelor of Science degree from the University of London in 1875. He was appointed professor of physics and mathematics at University College, Liverpool, in 1881. Lodge received the Doctor of Science degree in 1887. In 1900 he moved from Liverpool back to the Midlands and became the first principal of the new Birmingham University, remaining there until his retirement in 1919, overseeing the start of the move from Edmund Street in the city centre to the present Edgbaston campus. Lodge was awarded the Rumford Medal of the Royal Society in 1898 and was knighted by King Edward VII in 1902.
Accomplishments
Lodge is notable for his work on the ether, which had been postulated as the wave-bearing medium filling all space. He transmitted radio signals on August 14, 1894 at a meeting of the British Association for the Advancement of Science at Oxford University,Lodge, Oliver J (1932). This first broadcast demonstrattion by Lodge was two years before Marconi's first broadcast of 1896. In 1995 the Royal Society recognized this scientific break through at a special ceremony at Oxford University. Past Years: An Autobiography. New York: Charles Scribner's Sons, p231. one year before Marconi but one year after Tesla. Lodge improved Edouard Branly's coherer radio wave detector by adding a "trembler" which dislodged clumped filings, thus restoring the device's sensitivity. Lodge did other scientific investigations on lightning, the source of the electromotive force in the voltaic cell, electrolysis, and the application of electricity to the dispersal of fog and smoke. He also made a major contribution to motoring when he invented electric spark ignition for the internal combustion engine. Later, two of his sons developed his ideas and founded the Lodge Plug Company.
Lodge is also remembered for his studies of life after death. He first began to study psychical phenomena (chiefly telepathy) in the late 1880s. After his son, Raymond, was killed in World War I in 1915, Lodge visited several psychics and wrote about the experience in a number of books, including the best-selling "Raymond, or Life and Death" (1916). Altogether, he wrote more than 40 books, about the afterlife, aether, relativity, and electromagnetic theory.
Lodge had twelve children, six boys and six girls. Four of his sons went into business using Lodge's inventions. His sons Brodie and Alex created the Lodge Plug Company, spark plugs for cars and airplanes. Lionel and Noel created a company that produced a machine for cleaning factory smoke. Besides inventing the spark plug and wireless, Lodge also invented the loudspeaker, the vacuum tube (valve) and the variable tuner.
Lodge's papers were split up after his death. Some were deposited at the Universities of Birmingham and Liverpool and others at the Institute of Psychical Research at the University of London; a proportion of his scientific correspondence ended up at University College London.
Before he died, Sir Oliver Lodge declared that he would prove the existence of an afterlife by making public appearances to the living after his death. Since that event, however, there is no record of him ever having been seen or heard of by any living person.
