(Hans) Peter Israel Jost, CBE (25 January 1921 – 7 June 2016)[1][2] was a British mechanical engineer.
In 1966, Jost published a report which highlighted the cost of friction, wear and corrosion to the United Kingdom economy (1.1-1.4% of GDP).
[9] Jost was an apprentice at Associated Metal Works, Glasgow, then at Napier and Sons in Liverpool, where he won the Sir John Larking medal for a paper on measurement of surface finish.
Here he developed an innovative method of lubricating steam machinery, which saved energy and water by preventing scaling of boiler tubes.
[12] He was appointed a CBE in 1969, and was also honoured by the heads of state of France, Germany, Poland, Austria and Japan, and in 1992 became the first honorary foreign member of the Russia Academy of Engineering.
