It was on this day – Friday 24th July 1936 – that a speaking clock service was first introduced in Britain. The voice was that of London telephonist Ethel Jane Cain, who had won a prize of 10 guineas in a competition to find the right voice. Her voice was recorded optically onto glass disks in a similar way to a film soundtrack. You made use of the service by dialing the letters TIM (846) on a dial telephone.
As a result the service was often colloquially – and continuously referred to as “Tim”.
