Johann Peter Griess (6 September 1829 – 30 August 1888) was an industrial chemist Oxford Dictionary of National Biography and an early pioneer of organic chemistry. Griess was influential in the formation of modern dyes, first formulating the diazotization reaction of arylamines.
After most of the family possession had been spent, Griess 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.Peter Griess (1858) "Vorläufige Notiz über die Einwirkung von salpetriger Säure auf Amidinitro- und Aminitrophenylsäure," (Preliminary notice of the reaction of nitrous acid with picramic acid and aminonitrophenol), Annalen der Chemie und Pharmacie, 106 : 123-125. The discovery of a new class of chemicals convinced August Wilhelm von Hofmann to invite Griess to join him at his new position at the Royal College of Chemistry. During his time at the Royal College, he studied the reactions of nitrogen-rich organic molecules. It took him quite long to become accustomed to his new home in England, but the fact that he married in 1869 and founded a family made it clear that he did not intend to return to Germany, even though he was offered a position at the BASF. He left and started a position at the Samuel Allsopp & Sons brewery in 1862 where he worked until his retirement. His wife died after a long, severe illness in 1886; he survived her for two years and died on August 30, 1888. He is buried in Burton upon Trent.
