1931 Obituary 
HARRY DORNING BAILEY was the third son of the late Sir William H. Bailey, and upon leaving The Leys School, Cambridge, entered his father's firm at Manchester. He was subsequently manager of their London office.
During the War he served overseas with the Royal Engineers. He was a man of great courage and in addition to his service decorations possessed the Royal Humane Society's medal for saving life. He was largely instrumental in the invention of the turnstile and the penny-in-the-slot lock. The turnstiles on many of the piers round our coast still bear his name.
After the War he was mainly occupied in exploiting various preparations of his own, the most prominent of which was a liquid jointing material known as " Holdfast " which enjoys a considerable sale in the motor trade.
He died from injuries received in a motor accident near Derby on 2nd April 1931, at the age of 61. Mr. Bailey had been an Associate Member of the Institution since 1900.
