Charles Inglis

Who was Charles Inglis?

Sir Charles Edward Inglis, OBE, FRS was a British civil engineer. The son of a doctor, he was educated at Cheltenham College and won a scholarship to King's College, Cambridge, where he would later forge a career as an academic. Inglis spent a two-year period with the engineering firm run by John Wolfe-Barry before he returned to King's College as a lecturer. Working with Professors James Alfred Ewing and Bertram Hopkinson, he made several important studies into the effects of vibration on structures and defects on the strength of plate steel.

Inglis served in the Royal Engineers during the First World War and invented the Inglis Bridge, a reusable steel bridging system – the precursor to the more famous Bailey bridge of the Second World War. In 1916 he was placed in charge of bridge design and supply at the War Office and, with Giffard Le Quesne Martel, pioneered the use of temporary bridges with tanks. Inglis retired from military service in 1919 and was appointed an Officer of the Order of the British Empire. He returned to Cambridge University after the war as a professor and head of the Engineering Department. Under his leadership, the department became the largest in the university and one of the best regarded engineering schools in the world. Inglis retired from the department in 1943.
