Sir Oliver Joseph Lodge (June 12,1851 - August 22, 1940), born at Penkhull in Stoke-on-Trent, was a pioneer in the science and technology that led to the development of radio. Besides his work in physics, he was also known for his interest in the paranormal, and wrote a book about communicating with his son who had died in World War II. In his later life, he lectured widely on the existence of the spiritual world.

Biography

Born in Penkull, Staffordshire, Lodge was the eldest of nine children of Oliver Lodge, a vendor of supplies to the local pottery industry, and Grace Heath. He attended Adams' Grammar School, but his interest was sparked when, during a visit to London, he was encouraged to attend lectures on scientific subjects. Some of these were given at the Royal Society of London by John Tyndall, the renowed physicst. When Lodge was 16, he enrolled in educational courses in South Kensington, and succeeded in obtaining the highest grade of his class. When it became apparent that he excelled in scientific subjects, his father gave up the idea of having his son work for him, and Lodge was allowed to pursue a career in science. He obtained a scholarship to the Royal College of Science in London, where he studied from 1872-1873. In 1873 he entered the University College London, where the curriculum included advanced mathematics. Lodge graduated from this institution in 1875, and was awarded his doctorate in 1877. He was appointed professor of physics and mathematics at University College, Liverpool, in 1881.

Around this time, Lodge believed that he could produce light by creating a circuit that produced a high enough frequency of electromagnetic ocillations.

He worked with the physicist George Francis Fitzgerald to clarify the implications of Maxwell's theory of electromagnetism, and to explore the way in which electromagnetic waves could be generated from circuitry. At that time, however, Fitzgerald did not believe such waves could be produced, and Lodge, in deference to Fitzgerald's judgment, temporarily gave up his attempt to produce them. In 1883, Fitzgerald reversed his own position and calculated the energy of the waves that could be generated by electromagnetic oscillations.

Lodge became interested in lightning, and proposed the theory that lightning is an occillating phenomenon, meaning that a lightning bolt consists of a series of rapid back and forth surges of electricity, and not just a one-time one-way strike. According to Lodge's argument, a changing electric current produces an induced current in the opposite direction which acts more strongly than electrical resistance to prevent a lightning stroke from discharging through a lightning rod. As a result, he insisted that the lightning will not always take the path of least electrical resistance, but rather, of least electrical inductance. He experimented with the leyden jar, a crude device that holds a static electric charge, and compared its discharge in the form of a spark with lightining. While some of these ideas proved to be mistaken, they led to his discovery of electromagnetic waves.

During a series of lectures he gave in 1888 to demonstrate that lightning was not a one-strike phenomenon but rather a series of oscillations much like the ones observed in a leyden jar, he gradually realized that he could create what are called standing electromagnetic waves along a wire in much the same way as a single note and its overtones are produced in a musical instrument.

In July of 1888 Lodge submitted his results for publication in the form of a paper titled "On the Theory of Lightning Conductors," in which he clearly discusses the velocity, frequency and wavelength of electromagnetic waves produced and detected in in a circuit. Before the paper went to print, however, he discovered that Heinrich Hertz had already published a memoir where he was able to generate and detect waves transmitted across space. Lodge credited Hertz in a postscript to his own paper, which was published later that year.

Edouard Branly discovered that the conductivity of disaggregated materials such as metallic filings increased in the presence of an electric spark. Lodge attributed the increase of conductivity to radio waves generated by the electrical discharges, and in 1893 he created a device that used the same effect to detect their presence.

He called the device a coherer because the filings would cohere or clump together in the presence of electromagnetic radiation. Lodge would later patent this device, which would be used by Marconi in his work on radio waves.

In a lecture at the Royal Institution on the work of Hertz, who had passed away in 1894, Lodge described his coherer, and Alexander Muirhead, an electrical engineer, approached Lodge after realizing that electromagnetic waves could be used for communication. The two later formed a partnership under which Lodge marketed some of his patented inventions. Later that year in a similar lecture, Lodge demonstrated wireless communications using long and short pulses of radio waves.

Lodge, alone and in conjunction with Muirhead, patented his inventions relating to radio communication in Great Britain and in the United States. The two men formed the Muirhead Syndicate in 1901 to manufacture radio equipment, but in 1911, their patents were bought out by radio pioneer Guglielmo Marconi and the partnership was dissolved. In 1943, United States Supreme Court relieved Marconi of some of his U.S. patents in favor of Lodge and other early inventors of radio technology.

In 1900 Lodge moved from Liverpool back to the Midlands and became the first principal of the new Birmingham University, remaining there until his retirement in 1919. Lodge was awarded the Rumford Medal of the Royal Society in 1898 and was knighted by King Edward VII in 1902.

Accomplishments

AMERICAN PHILOSOPHICAL SOCIETY 1901 Lodge improved Edouard Branly's coherer radiowave detector by adding a "trembler," which dislodged clumped filings and restored the device's sensitivity. Lodge did 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. Lodge is notable for his work on the aether, which had been postulated as the wave-bearing medium filling all space.

On August 14, 1894, Lodge made the first demonstration of broadcasting radio signals at the annual meeting of the British Association for the Advancement of Science, at Oxford University. This was two years before Marconi's first broadcast of 1896.

He also made a major contribution to motoring when he invented electric spark ignition for the internal combustion engine (the Lodge Igniter). Later, two of his sons developed his ideas and in 1903 founded Lodge Bros, which eventually became known as Lodge Plugs Ltd.

In 1889, Lodge was appointed President of the Liverpool Physical Society, a position he held until 1893. The society still runs to this day, though under a student body.

Lodge was an active member of the Fabian Society and published two Fabian Tracts: Socialism & Individualism (1905) and co-authored Public Service vesus Private Expanditure with Sidney Webb, George Bernard Shaw and Sidney Ball

Lodge is also remembered for his studies of life after death. He first began to study psychical phenomena (chiefly telepathy) in the 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, including topics on the afterlife, aether, relativity, and electromagnetic theory.

Besides inventing the spark plug and wireless, Lodge also invented the moving-coil loudspeaker, the vacuum tube (valve), and the variable tuner.

Family

Lodge had twelve children, six boys and six girls. Four of his sons went into business using Lodge's inventions. His sons Brodie and Alec created the Lodge Plug Company, which manufactured spark plugs for cars and aeroplanes. Lionel and Noel founded a company that produced a machine for cleaning factory smoke.

Later life

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. Lodge is buried at St. Michael’s Church, Wilsford (Lake), Wiltshire.

Lodge's parents and siblings

Sir Oliver Lodge was the eldest of eight sons and a daughter of Oliver Lodge (1826-1884) - later a china clay merchant at Wolstanton, Staffordshire - and his wife, Grace (née Heath) (1826-1879). Sir Oliver's siblings included Sir Richard Lodge (1855-1936), historian; Eleanor Constance Lodge (1869-1936), historian and principal of Westfield College, London; and Alfred Lodge (1854-1937), mathematician.

Archives

Sir Oliver Lodge's letters and papers were divided after his death. Some were deposited at the University of Birmingham and University of Liverpool and others at the Society for Psychical Research and the University College London. Lodge was long-lived and a prolific letter writer and other letters of his survive in the personal papers of other individuals and several other Universities and other institutions.
