Invention
Eric Mowbray Merrifield is credited for the invention of the "Dolos", a concrete block used to stop coastal erosion. However, Kruger countered that claim by claiming that he was the inventor of the "Dolos" and that he had done so in 1963 after being instructed by the South African Railways and Harbours Administration to find a solution for the sea eroding the harbour. The block is reinforced in a complex shape weighing between 80 and 88 tonnes. It is used all over the world in harbours
