Vintage 6X8.25 form letter in German thanking all who wrote him for their congratulations on winning the Nobel Prize. Signed in blue fountain pen ink at the conclusion by Otto Diels. Scarce and in excellent condition with a photo of him affixed to the bottom left portion of the letter. (1876-1954) Otto Paul Hermann Diels was a German chemist. His most notable work was done with Kurt Alder on the Diels–Alder reaction, a method for diene synthesis. The pair was awarded the Nobel Prize in Chemistry in 1950 for their work. Their method of synthesizing cyclic organic compounds proved valuable for the manufacture of synthetic rubber and plastic. He completed his education at the University of Berlin, where he later worked. Diels was employed at the University of Kiel when he completed his Nobel Prize–winning work, and remained there until he retired in 1945.
