Johann Heinrich Ziegler (dye chemist)

Johann Heinrich Ziegler (born December 6, 1857 in Winterthur ; † January 30, 1936 in Zurich ) was a Swiss dye chemist and natural philosopher .

Life

Johann Heinrich Ziegler was born as the son of the manufacturer Emil Ziegler. He studied chemistry and was in 1883 Erlangen with a thesis About derivatives of beta-naphthylamine in the later Nobel Prize winner Emil Fischer PhD .

In 1884, Ziegler developed the yellow azo dye tartrazine in the laboratories of the Bindschedler factory for chemical industry in Basel ( CIBA ) . This was patented and produced by BASF in Germany in 1885 (DRP 34294). The process was first presented in 1887 in the reports of the German Chemical Society . Although the structure proposed by Ziegler was not confirmed, he was able to develop an alternative synthesis of tartrazine based on the idea that a hydrazone is the tautomeric form of an azo compound ( azo-hydrazo-tautomerism ). This manufacturing process was patented in 1893 (British patent 5693). Tartrazine was first as a light-fast wool dye and later as a food dye used.

Ziegler worked for a few years as a paint chemist in Basel and ran a company in Höngg , before he started looking for a universal formula as a private scientist at the turn of the century .

In 1901 Ziegler presented his so-called primordial light theory for the first time , which is based on the constant speed of the immaterial primordial light in aetherless space. From this theory he developed a universal formula for the world, by which he believed that he had solved the relationship between light and matter, color and chemical constitution. However, this has not been recognized by science. Ziegler raised allegations of plagiarism against Albert Einstein's theory of relativity , which he later fought vigorously, and against the color theory of the chemist and Nobel Prize winner Wilhelm Ostwald .

Ziegler had been a member of the Natural Research Society in Zurich since 1921 .
