In existographies, Frank Thone (64-6 BE) (1891-1949 ACM) (CR:16) (LH:3) (TL:19) was an American plant physiologist, ecologist, and science writer, noted for his introduction of the "CHNOPS+" or CHNOPS-plus, system of defining plants.
In 1936, Thone, in his article “Nature Ramblings: ‘Chnops,’ Plus”, seemingly independent of Ostwald, describes plants and animals, chemically, as “Chnops plus” [CHNOPS+] systems, via employing the following labeled by him visual:
- “Chnops: Six chemical elements are essential parts of protoplasm, the living substance itself. These are carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulphur. Their initial letters, which happen also to be their chemical symbols, have been arranged into a memory-saver word or mnemonic: CHNOPS — pronounced like the German word for strong liquor, Schnapps. There is a considerable quantity of the first four elements in protoplasm, and only a very little of the other two; but those small amounts are indispensable to life. Take them away, and protoplasm is no longer protoplasm; neither is it any longer alive.”

Thone, in other words, described solar-powered plants as systems comprised of the elements: carbon, hydrogen, nitrogen, oxygen, phosphorus, sulfur (CHNOPS) plus potassium and calcium, among others.
In 1922, Thone completed his dissertation, MS or PhD, entitled “Ecological Factors in Region of Starved Rock, Illinois”. In 1936, Thone was a staff writer for Science News Letters. In 1945, he was a Science Service biology editor and also was involved in radio-based promotions of science, e.g. national science talent searches.
