Doctor Chris Barnard’s first heart transplant in 1967 and Sasol’s oil-from-coal refinery are well known, but here are some of the lesser known inventions which came from South Africans.

Dolosse
Anybody who has visited harbours around the world would have seen large concrete blocks with a complex geometric shape, used to protect hardbour walls.

These large concrete blocks, known as dolosse (plural) or a dolos (singular), were invented by South African Eric Mowbray Merrifield in 1963, and are used around the world to protect harbour walls from the erosive force of ocean waves.
