. After most of the family possession were spent he had to start working at the chemical factory of Oehler in Offenbach am Main in 1856. This was only possible after the recommendation of Hermann Kolbe, who was head of the chemistry department in Marburg. The devastating fire of 1857 ended the production of chemicals at the factory and a changed Peter Griess rejoined Hermann Kolbe at the University of Marburg. His new enthusiasm for chemistry yielded the discovery of diazonium salts in 1858. The discovery of a new class of chemicals convinced August Wilhelm von Hofmann

Work

In 1858 he described the Griess diazotization reaction which would form the basis for the Griess test for detection of Nitrite
Nitrite
The nitrite ion has the chemical formula NO2−. The anion is symmetric with equal N-O bond lengths and a O-N-O bond angle of ca. 120°. On protonation the unstable weak acid nitrous acid is produced. Nitrite can be oxidised or reduced, with product somewhat dependent on the oxidizing/reducing agent...

. Most of his work related to brewing remained confidential, but his additional work on organic chemistry was published by him in several articles.
