Exactly fifty years ago, on 20 July 1969, Neil Armstrong was the first man to walk on the moon. But he had a little help from a sticky South African invention.
Pratley Putty, invented by Krugersdrop resident George Montague (Monty) Pratley, was used by NASA on the spacecraft.
Initially introduced to the market as Pratley Plastic Putty, the South African invention was used to attach some component of the landing craft, and was carried by astronauts in case repairs were needed on the moon.
This year, Pratley Putty also landed a new first: It will be cast as part of the SA Mint’s “South African inventions” commemorative coin series.
