Ludwig Knorr
Ludwig Knorr (2 December 1859 – 4 June 1921) was a German chemist. Together with Carl Paal, he discovered the Paal-Knorr synthesis, and the Knorr quinoline synthesis and Knorr pyrrole synthesis are also named after him. The synthesis in 1883 of the analgesic drug antipyrine, now called phenazone, was a commercial success. Antipyrine was the first synthetic drug and the most widely used drug until it was replaced by Aspirin in the early 20th century.
==Early life==
Ludwig Knorr was born to the wealthy merchant family in 1859. He grew up in the Sabbadini-Knorr company headquarters, located in the Kaufingerstraße in the center of Munich, and in the family house near the Lake Starnberg. After the early death of his father, the education of him and his four brothers lay in the hands of their mother. In 1878 Knorr received his Abitur and started to study chemistry at the University of Munich.
In the beginning, he studied under Jacob Volhard; then, after Volhard left for the University of Erlangen, Hermann Emil Fischer became his tutor. In the summer of 1880 Knorr worked with Robert Wilhelm Bunsen at the University of Heidelberg, and later assisted Adolf von Baeyer in Munich. When Emil Fischer became professor at the University of Erlangen, he asked Knorr to follow him.〔〔
