Edward Thomas Both (1908–1987) was an Australian inventor credited with the development of a number of medical, military and general-purpose inventions. These included a low-cost "iron lung", a humidicrib, the first portable electrocardiograph and the "visitel" – a forerunner to the modern fax machine.[1] His inventions gained him an OBE in 1940, and his work led to Both being given the moniker of the "Edison of Australia".[2]
Early life
Edward Both was born to James Alexander Both and Lucy Victoria (née Thomas) in the town of Caltowie, (near Jamestown) in South Australia. His parents had five children, of which Edward Both was the eldest. He was schooled in the local area, attending Caltowie Public and Jamestown High schools, and proved to be a good student – sufficiently so that when he was sixteen Both began studying at the Physics Department at the University of Adelaide. There he caught the attention of Kerr Grant, a physics professor, who subsequently appointed him as his personal assistant.[1][3]
In 1932 an electrocardiograph (ECG) developed by Both impressed Grant, and as a result Grant had a facility installed next to the University where Both could design and produce medical equipment.[1]
Both Equipment Limited
Both was soon considered to be the "foremost among designers of intricate tools of the medical trade in South Australia".[4] Both's cardiograph was an improvement on previous examples because it showed the heart's action instantly.[4] Working with his brother Donald, Both spent the next four years meeting orders for their electrocardiograph – for many years their products were the only commercially available direct-wiring models, and the ECGs they produced provided very accurate readings.[1][2]
An outbreak of poliomyelitis (polio) in Australia during 1937 saw a need for iron lungs to help those stricken with the disease. However, there were only a few such devices in Australia, and the US-built iron lungs were both expensive to purchase and hard to maintain. Thus the company was approached to develop an alternative. The result was the Both Respirator: a lightweight, comparatively inexpensive respirator made out of plywood (the name "iron lung" continued to be used by many, in spite of the wooden construction). The design proved effective, and the respirators were soon employed throughout Australia. Indeed, even as recently as 2003 there were several Both respirators still being used in private residences.[5]
In 1938 Both was in England to sell his ECG machines when he heard a request over BBC Radio for an iron lung to assist an individual suffering from poliomyelitis. With the assistance of the South Australian Agent-General, Both set up shop in a hired workshop and produced a few of his "cabinets", one of which was featured in a film produced by the Nuffield Department of Anaesthetics at Radcliffe Infirmary. The film was viewed by William Morris (Lord Nuffield), who was inspired to construct the devices at his Morris Motors LImited factory and offer them, free of charge, to any hospital in the Commonwealth that requested one. In the years that preceded World War II, approximately 1800 Both-Nuffield respirators were supplied to hospitals around the world.[5]
A request for information from America about Both's respirator was sent because of the lower cost of the device to fight poliomyelitis. Both arranged for an American company, K.N.Y Scheerer Corporation to produce the respirator in America.[6]
On his return from England Both created an ultracentrifuge for isolating very fine viruses. It was the first of its kind in Australia and could be used on the polio virus.[7]
World War II
During the war years Both continued to invent devices, often for the military. The electro-micrometer and electro-crack detector that he developed were designed to inspect the inside of gun-barrels for flaws,[8] and he was involved in work to develop guided torpedoes.[1] Other war time inventions included a three-wheeled electric van for use during petrol rationing that employed a new type of transmission and could turn on the spot,[7] additional medical equipment, (including a portable cardiograph that became standard military equipment during World War II),[7] and the "Visitel" – a device that could transmit drawings over long distances.[1][2] The visitel was deemed a secret project by the military, and because of the secrecy surrounding it the device was still unused by the end of the war.[7] By 1950 it had been installed at Randwick Racecourse to expedite totalisator operation.[9]
As a diversion during the war Both designed a Punch and Judy machine that showed Hitler being hit with an umbrella by Chamberlain whenever a coin was put in the slot. The money raised by the machine went to charity.[7]
Post-war
With the war over Both, now based in Sydney, continued to invent. With his brother he continued to work in medical equipment, developing a humidicrib, a new concept in design for blood transfusion equipment, and an electro-encephalograph. The electro-encephalograph designed and manufactured by Both Equipment Limited was used as an aid to the diagnosis of nervous disorders through its recording of the electrical activity of the brain.[10]
Both also worked in other fields: amongst his post-war projects were the electric scoreboards for the 1952 Davis Cup and the 1956 Summer Olympics in Melbourne. The Olympic scoreboard was made up of 10,000 light bulbs and could show all of the letters of the alphabet along with numerals.[1][7] Along with the scoreboards two versions of a pen recorder were developed and produced by Both: one was used as Woomera for weapons research and the other was used for Antarctic Research, the CSIRO, universities, hospitals and medical and industrial research.[8]
In 1953 Donald Both submitted a design for the humidicrib to the Queen's Coronation Gift Committee and it was accepted as a gift on behalf of the people of South Australia.[8]
Personal life
Both married Lily Eileen Maud Naughton in September 1937. Throughout his life Both enjoyed sports, especially swimming and tennis, although he had a reputation for possessing an "exhausting capacity for work".[1]
Both died at the age of 79 on 18 November 1987 while at Mount Beauty in Victoria.[1]
