Career

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. At 29, he became general manager of Trier Brothers, an international lubricants company, of which he subsequently became director. Here he developed an innovative method of lubricating steam machinery, which saved energy and water by preventing scaling of boiler tubes. By 1960, he was lubrication consultant to iron, steel and
