It was, however, his request that set in motion the invention of something that has gone into use across the world as the most successful means ever of absorbing and controlling the energy produced by waves pounding away at natural or man-made areas of coastline. Strangely, neither the inventor nor the port engineer sought to take out patents for what resulted from that request, although Merrifield was later to be granted, and he accepted, awards and recognition for which he was not really entitled. It appears that both men believed that, as they were employees of the state at the time, they were not entitled to reward for the invention. One day in 1963 Merrifield entered into a discussion with his draughtsman about designing a structure made from concrete that would be capable of protecting the East London Harbour breakwater from the battering waves. The draughtsman, 28-year old Aubrey Kruger, was a modest, quiet local man who rode to work every day on a red Vespa scooter from his home in Cambridge, one of East London’s suburbs. It was usual in those days at East London for people to return home at lunchtime each day and so, when Aubrey Kruger returned home by scooter that day the first thing he did was to commandeer his wife Daphne’s broomstick, from which he cut three pieces of wood which he nailed together in the shape of an H’ with one twisted leg. His daughter Sandra says she can remember her mother being rather angry, and having to shoo a chicken out of the kitchen with a shortened broomstick. She says her father based his idea on the dubbeltjie thorn. After lunch he returned to work where he placed the wooden model on Merrifield’s desk. According to Sandra, the name dolos came from her grandfather, Joseph Kruger, who was a carpenter working at the harbour dry dock at the time. He saw his son and others in the office playing with small models and asked “Wat speel julle met die dolos?” - dolos being the Afrikaans for knucklebones often used by sangomas and herbal doctors when divining. Children also used to play with these knucklebones. The Kruger family still has an original model of the dolos made by Aubrey using plaster of paris and left to dry in the garden. Aubrey Kruger’s son Lance retains this model in his possession.The drawings for the first dolos were completed in 1963, based on the shape devised in wood by Aubrey Kruger. As port engineer Merrifield was responsible for overseeing the project and signing off all plans. Kruger enjoyed seeing the development of his invention which resulted in much excitement in the family. At the end of 1966 Kruger was transferred to Durban and was given a copy of the amendment to the design dated July 12, 1966 drawn by Aubrey Kruger and signed by Mr Merrifield, as a farewell gift from the East London office. |
