[Clemens Alexander Winkler (December 26, 1838, Freiberg (Saxony) — October 8, 1904, Dresden) was a German chemical technologist who discovered the chemical element germanium (1886), the ”fortifier” of D. I. Mendeleev's theory of periodicity. In addition to the isolation and study of germanium, Winkler was engaged in the analysis of gases. He published a book on this subject — ”A guide to the technical study of gases in technical production” (1884). In this book, Winkler described the three-way crane he invented. He also developed an industrial method for the production of sulfuric anhydride by the interaction of sulfur dioxide and oxygen when heated in the presence of platinized asbestos, thus laying the foundations for the contact industrial method for the production of sulfuric acid. In addition, Winkler predicted the existence of silicon monoxide, and was the first to attempt to produce it by heating silicon in 1890. However, the experiment was unsuccessful, because he could not bring the mixture to a sufficiently high temperature using an oven. Due to the lack of reaction, Winkler incorrectly concluded that SiO does not exist, even though three years earlier Charles F. Maybri has already reported that this compound is formed when silica is reduced by coal. However, Henry Noel Potter, an engineer from Westinghouse, repeated Winkler's experiment fifteen years later in an electric furnace, which allowed him to increase the reaction temperature by several hundred degrees and observe the release of SiO.]
