Don Ritchie’s window-watching had a far greater purpose. Since l964 he has saved at least 160 lives, though some say the true figure is much higher. Mr Ritchie, who died this week at the age of 86, was known as the Angel of the Gap, a title earned for persuading people not to throw themselves off the notorious Australian suicide spot.
Like Beachy Head on the Sussex coast, the sheer cliffs at the mouth of Sydney harbour have long acted as a magnet to those who have lost all hope. But thanks to his calm voice and sympathetic manner, Mr Ritchie offered a helping hand to the desperate by engaging them in conversation on the cliff-top in their hour of need.
