Meredith Thring. Meredith Wooldridge Thring (17 December 1915 – 15 September 2006) was a British inventor, engineer, futurologist, professor and author.

Education and career
Thring was born in Melbourne, Australia, but moved to England when he was four years old.  His school was Malvern College. He obtained a double first class degree in Mathematics and Physics at Trinity College, Cambridge in 1937. He then joined the British Coal Utilisation Research Association, becoming Head of its Combustion Research Laboratory. In 1940, he married Margaret Hooley (died 1986), and they had two sons and one daughter.

In 1946, Thring became head of the newly formed Physics Research group of the British Iron and Steel Research Association. In 1950, he moved to the University of Sheffield, becoming professor and head of the Department of Fuel Technology and Chemical Engineering in 1953. In 1964, he took up the position of head of the Department of Mechanical Engineering at Queen Mary College of the University of London, where he remained until his retirement in 1981. He died in Exmouth, Devon.

Honours
Thring was awarded the Student Medal of the Institute of Fuel in 1938, and the Hadfield Medal of the Iron and Steel Institute. From 1962 to 1963 he was President of the Institute of Fuel. In 1964 he was awarded a ScD degree from University of Cambridge. He was a Fellow of the Institute of Physics (FInstP), the Energy Institute (FEI), the Institution of Mechanical Engineers (FIMechE), the Institution of Engineering and Technology (FIET), and the Institution of Chemical Engineers (FIChemE). He was one of the first Fellows of the Royal Academy of Engineering (FREng).

Work
Thring was a visionary who changed from science to engineering "because he wanted to make the world a better place". In his 1977 book How to Invent, he wrote "One can envisage a society in which man lives in near-equilibrium with his environment, with the minimum use of raw materials by fuel economy, complete recycling of all metals, no throw-away goods, all consumer goods built to last many decades, and near zero pollution." In the same book he describes domestic and gardening tools, Intermediate Technology for less developed countries and robots to take the place of people in dangerous situations. However, these were not just imagining. At the University of Sheffield and Queen Mary College he was actively involved in robotics. He produced a stair-climbing robot, an autonomous fire-fighting robot, and one for clearing a table.  After his retirement he founded a charity called Power Aid to help developing countries. In 1969 he predicted a future in which factories would be largely automatic, controlled by a central computer, and supposed that this would reduce the human working week to 10 or 20 hours.

He studied combustion and other forms of energy generation, and was one of the founders of the International Flame Research Foundation.  This knowledge of energy was shown in his 1974 book Energy and Humanity which called essentially for a more rational and sustainable approach, with control of pollution.  He was also known as a teacher, and for his belief that engineers had an ethical obligation to improve life for all, but notably the underprivileged and disabled.
