1946 Obituary

Colonel HENRY ALEXANDER STENNING, O.B.E., T.D., whose death occurred in September 1945, was for thirty years managing director of the Superheater Company, Ltd., Westminster, the development of which from quite a small concern, was largely due to his initiative and resource.

He was born in 1870, and received his general education at Sherborne School. On the conclusion of three years' apprenticeship at the Ashford locomotive works of the South Eastern Railway in 1891, he became a special student in the engineering department of the City and Guilds Central Institute, South Kensington, and was trained under the late Professor Unwin for two years. For a brief period he was employed in the drawing office of the London and South Western Railway at Nine Elms.

In 1896 he was appointed managing director of Messrs. De Winton, Ltd., general engineers and ironfounders, Carnarvon.

He resigned office in 1905, on receiving from the inventor the appointment of agent for the Schmidt Superheater Company. His energetic personal supervision, aided by sound mechanical engineering training, enabled him to overcome the practical difficulties of the new venture. At first the activities of the firm were confined to locomotive practice, but in 1911 the company entered the field of marine installations. The extension of the superheater to boilers in large power stations dated from 1925, notable examples being those of Barking and Fulham.

Colonel Stenning retired from the board of directors in 1934, but continued to act in an advisory capacity. He had been a Member of the Institution since 1901. Colonel Stenning had a long connection with the Territorial Army, and received the awards of the O.B.E. and T.D.
