Justus von Liebig (1803-1873) was one of the pioneers of elemental analysis and is often called the father of organic chemistry. He was working from 1824 - 1852 as professor in chemistry at the university in Gießen. His most famous development is the "kali-apparat", a five-bulb device. The Liebig five-bulb apparatus contains the basic techniques of the apparatus, for which Maximillian Dennstedt applied for a patent in 1903. This patent was the start for the spread of industrial elemental analysis. In Justus von Liebig's blog articles, we imagined what he would tell us nowadays about the history of elemental analysis.
