) was a German chemist and professor emeritus.
Prinzbach studied chemistry at the University of Freiburg and received his PhD under Arthur Lüttringhaus. He joined William von Eggers Doering at Yale University for postdoctoral work. In 1962 he completed his habilitation
Habilitation is the highest university degree, or the procedure by which it is achieved, in many European countries. The candidate fulfills a university's set criteria of excellence in research, teaching and further education, usually including a ...

Of his many research interests in organic chemistry, including photochemistry with unusual chromophores, synthesis of new carba-/hetera cages, radical cations, dications, total synthesis of aminoglycosid antibiotics, and enzymes, Prinzbach was probably best known for the pagodane route towards dodecahedrane. In the course of his research, the phenomenon of σ-bishomoaromaticity was discovered as an extreme case of chemical bonding. The final landmark the development of dodecahedrane chemistry over many years was the preparation and characterisation of C20 fullerene
C, or c, is the third letter in the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''cee'' (pronounced ), plural ''cees''.

σ-Bishomoaromaticity is an extreme case of the chemical bond and the aromaticity. It was found by the Prinzbach when they synthesized dodecahedrane via the Pagodane routeR. Herges, P. v. R. Schleyer, M. Schindler, W.-D. Fessner J. Am. Chem. Soc. 1991, 113, 3649.Honors
