The quoted article cites two previous findings of the use of salt water. However there is the question as to whether this idea ever became common knowledge. The fact remains that film had to be processed on shipboard during WWII and the use of salt water was found to be beneficial. It is not uncommon in science to find that the same fact has been "discovered" more than once. Roger Bacon is credited with the discovery of gunpowder even though it had been known for some time in China.

A rock pile ceases to be a rock pile the moment a single man contemplates it, bearing within him the image of a cathedral.
