32853 Döbereiner           Discovered 1992 Sept. 21 by F. Borngen and L. D. Schmadel at Tautenburg.
Johann Wolfgang Döbereiner (1780-1849), professor of chemistry at Jena and creator of the first chemical educational laboratory, was a lifelong friend of Goethe. He discovered the catalytic properties of platinum and observed similarities among elements that anticipated the periodic system of elements.
