Its inventor, William Radam, published a book, Microbes and the Microbe Killer (189o) describing at great length his quest for a cure for his own rheumatism, which he believed to have been caused by microbes. A florist and nurseryman, Radam associated the killing of microbes in the human body with the killing of pests on plants. He sought to find a harmless antiseptic gas that would cleanse the human body just as fumigation destroyed the bugs in his greenhouses.
In the book, Radam is unspecific about the methods that led to his claimed success, saying vaguely “A little more improving, and I had the antiseptic that proved to be an antiseptic, without having experimented upon my body.” (p49, revised edition 1895) Analyses, however, showed that the remedy was more than 99% water, with traces of sulphuric acid, sulphurous acid and ash (Journal of the A.M.A., 1910)
