Anthony George Maldon Michell FRS (21 June 1870 – 17 February 1959) was an Australian mechanical engineer of the early 20th century.
Michell was born in London while his parents were on a visit to England from Australia to which they had emigrated 17 years earlier. The family returned to Maldon, Victoria, in 1872, where young Anthony attended one of the state primary schools newly established in that area. He later returned to England and attended the Perse Grammar School while his elder brother, John Henry, attended Trinity College, Cambridge. On leaving school, A.G.M. Michell matriculated and spent one year as a non-collegiate student at Cambridge. In 1889, he returned to Australia and studied civil engineering at the University of Melbourne, graduating in 1895. For the next two years he obtained practical experience in structural engineering with the firm Johns and Waygood. He then returned to University, and completed a Master of Civil Engineering degree in 1899. The next few years were spent in hydraulic engineering and it was not until the early 1900s that he turned his attention to the theory of lubrication.
The Michell principle, previously known as film lubrication, was originally observed and investigated by Beauchamp Tower and Osborne Reynolds. Several years elapsed before their theories were put into practice by A.G.M. Michell, who first showed how it was possible to apply film lubrication to flat thrust surfaces and journal bearings, the result being the now widely known and universally adopted Michell bearing. Arising from Michell's research work on the mechanical properties of liquids and the mathematical studies of fluid motion viscosity and lubrication, a patent was taken out in England and Australia on 16 January 1905. In a few years his invention completely revolutionised thrust bearing technology, particularly in the field of marine propulsion and steam turbines.
The company of Michell Bearings Limited [1] was established in Newcastle upon Tyne, England, in 1920. Principal shareholders at that time were Vickers, Fairfield Rowan, John Brown Engineering and Cammell Laird.
